Novelty (locomotive)
Encyclopedia
Novelty was an early steam locomotive
built by John Ericsson
and John Braithwaite to take part in the Rainhill Trials
in 1829.
It was an 0-2-2
WT locomotive and is now regarded as the very first tank engine
. It had a unique design of boiler and a number of other novel design features (perhaps explaining the choice of name). Unfortunately, several of the major components had significant design weaknesses which ultimately resulted in its failure at the Trials.
with steam pumps. These used a boiler
designed by Ericsson and were built in the London
works of John Braithwaite.
These fire engines were known for their ability to raise steam quickly and looked very similar to Novelty.
Charles Vignoles has also been associated with Novelty, but his practical involvement is not known. He may have aligned himself with the engine because of a continuing feud with George Stephenson
.
Novelty was constructed in the London
Workshop belonging to Braithwaite and transported to Liverpool by boat. There was no time to test Novelty in London before transportation, and following test runs at Rainhill
before the trials, modifications were carried out with the help of Timothy Hackworth
.
and most steam locomotives since.
The most prominent feature for the boiler is the vertical copper firebox (the large vessel to the right in the illustration here). Within the vertical vessel was the inner firebox and the space between the two was filled with water (to a level just about the same as the driver’s ankle). (Coke
) fuel was added from the top, where a tube passed down through the top of the firebox. This firebox construction was not dissimilar to some types of vertical boiler, but this was only part of Ericsson’s design.
Like George Stephenson
, Ericsson understood that a large area was needed to extract heat from the hot gases. This he did in a long horizontal tube filled with water which ran under the full length of the engine. It can be seen of the illustration here, sticking out to the right, with the vertical chimney attached to it. Within the horizontal section was a tube carrying the hot gases, this formed an ‘S’ shape so the gases made three passes through the water. This ‘S’ shaped tube was also tapered causing the gases to speed up as they cooled down. In practice this tube is almost impossible to clean.
The resulting boiler was the shape of a hammer
and was required to be fitted to the frame
before the footplate
, cylinders or blower could be added.
The boiler used a ‘Forced Draught’ provided by a mechanical blower (the triangular structure on the right in the illustration). This forced air along a pipe and into the sealed ashpan (below the fire). Very few steam locomotives have ever used a forced draught like this, the main reason is that in order to add fuel either the draft must be stopped or some form of airlock
fitted. Novelty used an airlock to feed the fuel in, but there was still a chance of flame and hot gases being blown into the face of the fireman.
The blower was driven from the rods linking the cylinders to the wheels, thus the draught was proportional to the speed of the engine, not to how hard it is working as with a blastpipe
. It is assumed that either the blower was worked by hand when the engine was standing or the drive wheels were lifted off the rails. Details of the blower design are not known for certain.
Water was forced into the boiler using a pump
driven off one of the cylinders (this was normal practice at the time).
) caused problems with poor riding and did not work well with the springs.
On Novelty, the cylinders were mounted vertically towards the rear of the engine (to the right of the men in the illustration). Directly below were bell crank
s which changed the drive to horizontal. Connecting rods linked the bell cranks to the crank axle
(the axle on the left in the illustration).
The valve gear
took a similar route to the drive. One effect of this was it had many pins and links, resulting in lost motion.
The wheels themselves were of the suspension type (similar to a bicycle wheel
).
It is easy to think that Novelty is an 0-4-0
locomotive as it had equal sized wheels, however is actually an 0-2-2
WT. Only the wheels under the firebox (those to the left on the illustration here) were driven, the other wheels were not connected to the drive in any way.
as the fuel was carried in baskets on the footplate and water was in a well tank between the wheels.
As one of the rules for the Rainhill Trials related to the weight of the engine without a tender, a special allowance had to be made for Novelty.
In the preparations for the trials, Novelty was shown to be very lightweight and very quick to raise steam.
Novelty was the first locomotive to be tested. Starting on the second day of the trials, it began the planned series of runs but very quickly the blower failed and repairs had to be made. The repairs took up all of the next day. However, when Novelty next ran the water feed pipe burst and more repairs had to be made, which seem to have included a seal on the boiler. At the time, the boilers were sealed with a cement
-like substance which required days - if not weeks - to set properly. Time would not allow this and the seal quickly failed once the trial runs were restarted.
The recurring boiler problems prompted Ericsson and Braithwaite to withdraw from the Trials.
Before it failed, the Stephensons were said to be seriously worried by Novelty, as it was well-suited to meet the conditions of the trial. For one thing the Stephensons considered the weight to be pulled to be too light for a practical railway.
Two further engines were built by Ericsson and Braithwaite named William IV and Queen Adelaide. These were generally larger and more robust than Novelty and differed in a number of details (for example, it is thought that a different design of blower was used which was an ‘Induced Draught’ type, sucking the gases from the fire). The pair ran trials on the Liverpool and Manchester Railway
but the railway declined to purchase the new designs.
Novelty was transferred to the St Helens and Runcorn Gap Railway
and worked there for a few years. During its time there (around 1833) it received new cylinders and a new boiler.
Somehow, all the wheels and both cylinders (assumed to be the original one not those from the 1833 rebuild) survived.
During 1929 the original wheels and one cylinder were incorporated into a full scale, non-working model that is now on display in the Manchester Museum of Science and Industry. This early replica was rebuilt in 1988 and currently includes batteries and an electric motor to allow it to move (all wheels are driven making the engine a 4wBE), although the steam components are non-functional. The other cylinder is on display at Rainhill
Public Library.
No other British locomotives are known to have been built in this style. Comparisons are made with 20th century vertical boilered engines such as those by Sentinel
of Shrewsbury
, but in fact the principles were very different.
. It was a fully working replica that was built to look correct when display at the planned event; however many changes were made to reduce the construction costs and meet modern standards. It has been suggested that the replica was built to last no longer than the 3 days of the Rocket 150 event.
Some of the differences between the original and replica are:
For a reason that is not fully understood, the wheels of the replica were built with very narrow treads. It is possible that wheels were scaled off a model in the London Science Museum
. As a result it was unable to travel over modern pointwork
.
During the Rocket 150 event, Novelty was carried on a Well wagon, supported in such a way as to allow the engine to be run and its wheels to rotate freely.
Following the Rocket 150 event, Novelty was steamed on a small number of occasions in Manchester
. Around 1982, it was sold to the Swedish Railway Museum
, Gävle
, and left the UK
.
During July 2002, Novelty was collected from its then home in the Angelholm
, for use in a TV programme. It was returned to Sweden
during the spring of 2003, but made a short visit to the Museum of Science and Industry in Manchester
during the autumn of 2005.
TV programme "Timewatch
– Rocket and its Rivals" the replica of Novelty was transported to the National Railway Museum
in York
. Here it was completely dismantled to allow examination of the boiler and working parts. Several items needed to be attended to before the locomotive could be run:
Of this work, the major item was the modification of the wheels. The solution adopted by the National Railway Museum Workshop was to employ a metal fabricator to cut four rings from 40-mm-thick steel plate. These were cut with enough precision not to need any further machining. The rings were then bolted to the existing wheels and were a complete success.
Following re-assembly, the locomotive was steam tested at York before transport to Carrog station
on the Llangollen Railway
. Early tests showed up two major problems: firstly the linkage to the blower was not strong enough, and secondly operating the water feed pump caused very serious priming
of the boiler. It was later shown that the feed pump was five times the size of that required for the engine. This caused air to be fed into the horizontal boiler tube probably caused the priming.
To fully recreate the Rainhill Trials, 20 return runs along a section of the Llangollen Railway were required (between Carrog and Glyndyfrdwy stations
). Novelty was only able to complete 10 runs before the fire became completely filled with clinker
. The inability to clear clinker from the fire in this type of boiler was a major problem, the only way being to drop the fire completely and start again.
During the runs for the restaging of the trials Novelty was run with an electric fan (powered by a petrol generator) in place of the blower. Even allowing for this in the final calculation Novelty was much more efficient than Sans Pareil
For the Restaging, the replica of Novelty was too slow to meet the requirements of the original trials and did not complete the course. The maximum speed attained at any point was 17 miles per hour (27.4 km/h), possibly because the main steam pipe from the boiler was restricting the flow to the cylinders. The valve gear was also set incorrectly (indicated by the odd noise of the exhaust beats).
With all the obvious differences between the original and the replica, added to the fact that the locomotive crew used had only four days experience of operating the locomotive, it cannot be said that in this restaging of the trial the replica of Novelty gave the performance that the original could have achieved if more time had been made available in 1829.

Building the Engine
It is said that Ericsson and Braithwaite only found out about the Rainhill Trials seven weeks before the event was due to take place, when Ericsson received a letter from a friend referring to a "Steam Race". This incredibly short space of time has led people to suggest that Novelty is in fact a converted fire engine. It is more likely that it used many of the same parts as their fire engines and these parts may even have been built for an existing order and diverted to Novelty.Novelty was constructed in the London

The Boiler

As one of the rules for the Rainhill Trials related to the weight of the engine without a tender, a special allowance had to be made for Novelty.
Performance in the Trials
Novelty was the crowd’s favourite to win the Trials. This may be because it looked like a steam carriage (which people associated with speed and improvements in transport) or it may be because it did not look like a typical colliery engine of the time. In the demonstration runs that took place on the first day of the trials, Novelty did not disappoint, managing a speed of around 28 miles per hour (45.1 km/h)In the preparations for the trials, Novelty was shown to be very lightweight and very quick to raise steam.
Novelty was the first locomotive to be tested. Starting on the second day of the trials, it began the planned series of runs but very quickly the blower failed and repairs had to be made. The repairs took up all of the next day. However, when Novelty next ran the water feed pipe burst and more repairs had to be made, which seem to have included a seal on the boiler. At the time, the boilers were sealed with a cement

-like substance which required days - if not weeks - to set properly. Time would not allow this and the seal quickly failed once the trial runs were restarted.
The recurring boiler problems prompted Ericsson and Braithwaite to withdraw from the Trials.
Before it failed, the Stephensons were said to be seriously worried by Novelty, as it was well-suited to meet the conditions of the trial. For one thing the Stephensons considered the weight to be pulled to be too light for a practical railway.
After the Rainhill Trials
Once all the repairs were completed, Novelty made a number of successful demonstration runs but it was too late to have any effect on the competition. It is sometimes claimed that one of these demonstration runs included the locomotive reaching a speed of 60 miles per hour (96.6 km/h), but there is little to back this up and it may be a misinterpretation of a newspaper report trying to give an impression of the great speeds that the Rainhill engines were achieving.Two further engines were built by Ericsson and Braithwaite named William IV and Queen Adelaide. These were generally larger and more robust than Novelty and differed in a number of details (for example, it is thought that a different design of blower was used which was an ‘Induced Draught’ type, sucking the gases from the fire). The pair ran trials on the Liverpool and Manchester Railway

is "pop" type rather than "dead weight".
- Firstly the pop valves were a type used in industry; secondly the dead-weight type could be held down (so it would never work properly); and thirdly a dead-weight valve tends to bounce and thus waste steam.
- The boiler of the replica contains approximately twice the volume of water
- This is mainly as a result of the construction methods used (flanged joints on the barrels and standard steel pipe for the flue tube). It is also gave bigger water spaces between the inside and outside plates. In consequence, the fire grate must have considerably smaller than on the original.

- Full boiler inspection for insuranceInsuranceIn law and economics, insurance is a form of risk management primarily used to hedge against the risk of a contingent, uncertain loss. Insurance is defined as the equitable transfer of the risk of a loss, from one entity to another, in exchange for payment. An insurer is a company selling the...
purposes - Minor boiler repairs
- Modifications to the wheels to allow safe operation on normal railways
- Cleaning and repainting of the water tank
- Releasing of several water valves that had seized
- Partial repaint
Of this work, the major item was the modification of the wheels. The solution adopted by the National Railway Museum Workshop was to employ a metal fabricator to cut four rings from 40-mm-thick steel plate. These were cut with enough precision not to need any further machining. The rings were then bolted to the existing wheels and were a complete success.
Following re-assembly, the locomotive was steam tested at York before transport to Carrog station
Carrog railway station
Carrog railway station in Denbighshire, Wales, was formerly a station on the Ruabon to Barmouth line. It was to have closed to passengers on Monday 18 January 1965 but closed prematurely on 14 December 1964 due to flood damage. It was reopened in 1996 as part of the preserved Llangollen Railway...

Llangollen Railway
The Llangollen Railway is a volunteer-run preserved railway in Denbighshire, Wales, which operates between Llangollen and Carrog; at long, it is the longest preserved standard gauge line in Wales and operates daily in Summer as well as weekends throughout the Winter months using a wide variety of...
. Early tests showed up two major problems: firstly the linkage to the blower was not strong enough, and secondly operating the water feed pump caused very serious priming

of the boiler. It was later shown that the feed pump was five times the size of that required for the engine. This caused air to be fed into the horizontal boiler tube probably caused the priming.
To fully recreate the Rainhill Trials, 20 return runs along a section of the Llangollen Railway were required (between Carrog and Glyndyfrdwy stations

). Novelty was only able to complete 10 runs before the fire became completely filled with clinker

. The inability to clear clinker from the fire in this type of boiler was a major problem, the only way being to drop the fire completely and start again.
During the runs for the restaging of the trials Novelty was run with an electric fan (powered by a petrol generator) in place of the blower. Even allowing for this in the final calculation Novelty was much more efficient than Sans Pareil
For the Restaging, the replica of Novelty was too slow to meet the requirements of the original trials and did not complete the course. The maximum speed attained at any point was 17 miles per hour (27.4 km/h), possibly because the main steam pipe from the boiler was restricting the flow to the cylinders. The valve gear was also set incorrectly (indicated by the odd noise of the exhaust beats).
With all the obvious differences between the original and the replica, added to the fact that the locomotive crew used had only four days experience of operating the locomotive, it cannot be said that in this restaging of the trial the replica of Novelty gave the performance that the original could have achieved if more time had been made available in 1829.
Other Locomotives Named Novelty
Excluding the original and the replicas, the following locomotives have carried the name Novelty- LNWRLondon and North Western RailwayThe London and North Western Railway was a British railway company between 1846 and 1922. It was created by the merger of three companies – the Grand Junction Railway, the London and Birmingham Railway and the Manchester and Birmingham Railway...
