DB Class 218
Encyclopedia
The DB Class 218 are a class of 4 axle, diesel hydraulic locomotives acquired by the Deutsche Bundesbahn

The class represents the final major revision of the DB V 160 family of locomotives
DB V 160 family

Background, history and design

The locomotives of series 218 were the last of the V 160 family to be developed; the main new feature was the use of a single engine to provide tractive power as well as electrical train heating when required (via an attached generator), the simplification over the two engined DB Class 217 was preferred, and was made possible by the availability of a higher powered (~1840 kW) engine compared to the original DB Class V 160

 on both passenger and freight trains outside electrified sections.

The turn of the second millennium and the preceding few years saw a change from locomotive hauled trains to increasing use of 'diesel railcars' (or DMUs, diesel multiple units). This led to a reduction in the demand for these locomotives on passenger services, with many falling out of use, or only finding work pulling freight trains, nevertheless, in 2000 the locomotives were still in use on mainline long distance trains.

By January 2008 there were approximately 220 copies still active.

Technical information

The design of the series as fundamentally the same as the rest of the V 160 family: all four axles are driven via cardan shafts by a Voith two speed hydraulic transmission which in turn is driven by a diesel engine, fuel and oil are located between the bogies under the main frame, on either side of the centrally located transmission, there are two cabs (which have slightly different windows). Externally the machines are very similar to the other members of the class, being of the longer variant at 16.4m

The tractive and braking forces are transmitted to the main mass of the locomotive via transverse beams attached to the main longitudinal supporting beams, the superstructure is made from sheet steel, forming a shell.

The framework supported on coil springs on the bogies, from 218 299 onwards flexicoil suspension

 was used, per bogie side and from the bogies.

There are two walkways connecting the cabins inside the body.

Engines

Over time, several diesel engines have been used as propulsion; the first series received the MA MTU 12V 956 TB10 with 2500 hp

Because of the available power at rail being reduced when operating at full electric heating power some machines were fitted with a French 16 Pielstick PA4 V200 engine with around 2700 hp built under license by KHD.

, as well as the original engines being badly worn, or in an attempt to improve efficiency, a number of upgrades have been investigate or fitted, including:
  • TB11 engines fitted with emission reducing kit.
  • Electronic engine management fitted to TB11 engines.
  • Testing of entirely new engines, leading to:
    • Procurement of numerous 16 V R40/41 MTU engines as replacements
    • 4 locomotives fitted with Caterpillar Inc engines


Following the upgrades most of the class have either emission impoved TB11 engines or MTU 4000 engines.

Since 1985, the locomotives have had additional engine exhaust devices fitted on the roof with a scoop like appearance - the purpose of these is to direct the exhaust flow, preventing overhead wire being coated by any particulate or condensed emissions. The 'scoops' also increase the exhaust flow speed, by reducing the diameter of the exhaust - thus launching the combusted vapours higher in the air, and reducing the likelihood of passengers being coated with engine smoke.

Electrical equipment

The Indusi safety system is usually a Lorenz Indusi I-60. The original 36-pin inter-unit electrical connectors allows double traction control, auto door locking when not at a standstill, and can transmit driver announcements when attached to a passenger train, in addition to equipment for passenger information systems.

Originally the electrical power from the generator for the carriages was controlled with a simple Cycloconverter

Liveries

The first locomotives were delivered in the usual 'crimson' (RAL 3004) of that time. In 1974 218 217 and 218 218 were used as test vehicles for new colour schemes : 218 218 was the first locomotive in the new ocean blue-beige (turquoise/cream) finish (RAL 5020/1001). 218 217 received an experimental livery in the TEE

 red and beige (RAL 1001/3004).

The turquoise/cream colour became a new standard for the 218, whilst the 218 217 in the burgundy and beige remained a loner, for almost thirty years, until 753 001 (ex 217 001) became the second locomotive from the V160 family to receive this colour scheme.

Variants

A number of locomotives have been rebuilt and/or reclassified due to changing requirements:

DB Class 218.9

The DB Class 218.9 resulted from the Deutsche Bundesbahn's flirtation with diesel locomotives boosted by gas turbine engines in the 1970s. Problems with gas turbine engine lifespan, and reduced fuel efficiency, coupled with two turbine failures resulted in the small class of eight Class 210 machines being rebuilt as class 218.9 at the beginning of the 1980s. This subclass was number 218-901 to 218-908. They were decommissioned and scrapped between 2004 and 2006.

 and were in particularly good condition. For this task the locomotives needed to be approved for running at 160 km/h (the same maximum speed at which the original Class 210 had run). The original hydraulic transmission was rated in its upper gear to 160 km/h, but the drive shafts needed to be uprated for the increased speed.. The individual locomotive numbers were preserved - thus DB 218 430 became DB 210 430.

Following the full electrification of the line the locomotives returned to normal stock duties, in December 1998 the locomotives were rebuilt again and became Class 218 machines once again.

DB AG Series 225.8

Class 215 and Class 218 locomotives transferred to DB Railion for freight work were renumbered as Class 225, with the Class 218 locomotives forming the sub-series 225.8.

Operations

The Class 218 was a successful design made with the most modern and sophisticated components that were available in 1968. With a relatively high speed of 140 km/h, the locomotives proved useful on TEE, and with n-wagons

 with which they operated well past the year 2000.

Furthermore, after the dissolution of the GDR, and the merging of the two German railway systems they proved useful again on non-electrified sections of the former Deutsche Reichsbahn, however in the former West Germany some intercity services began to be operated by the DB Class 232 and 234 locomotives.

In 2000 there were 415 active machines, at this time also began the first decommissioning of machines that shown to be were in a bad state of repair on their scheduled inspections. At this time DBAG began to economise its fleet:
  • The locomotives with serial numbers 101 to 399 were to be kept until 2003, but then be either retired, transferred for internal use, or sold to DB AutoZug.
  • The 218.4 locomotives capable of push pull operation were to be used with double decker passenger coaches.
  • The prototypes locomotives were reclassified as Class 225.8 and transferred to DB Cargo for freight use.
  • The 218.8 sub-class modified for towing ICE trains remained in service.


In March 2008 were 235 active machines, or about 60% of the total Serienloks.
