Some of the important research projects:
1. Construction of automatic train control system ATC, PATC
2. Construction of hybrid locomotive
3. Operating locomotive GT26 simulator system
4. Design and construction of rail bus and two purposes rail truck
5. Design and construction of the intelligent barrier system of railway level crossings

7. Study on the decreasing of passenger train traveling time (Tehran- Miane- Tehran)
8. Design and construction of wheel and rail wear test system
9. considering the track electrification criteria in Iran
Titles of some glories and measures:
1. Taking the certificate of ISO 9001; 2000 in 2003.
2. Selecting this center as a sample research center in ministry roads and transportation for two times
3. selecting at least, 4 superior researchers from the center staffs in the ministry roads and transportation and in Iran
4. holding 7 seminars on rail transportation
5. holding 6 seminars on safety promotion and accident prevention
6. presenting papers in international conferences
7. presenting papers in national conferences, UIC conferences, international level crossing conference in Canada, IHHA conference, WCRR conference, international symposium of Turkish railway, international safety railway conference
8. connection with international association such as UIC
was designed and contracted by railway research center MATRAI in 1999 and the sample was ready in 2000. It was a G12 locomotive that was converted to hybrid by using a 200KW diesel generator and batteries and also was equipped with 2 AC traction motors (out of 4) retrofit in the cover of the DC traction motors. It was inaugurated by missed Dr, Dadman the minister of road and transportation in 2001.
In 1992 the GE locomotive was introduced that had AC-DC traction system with 26% AWA and in 2002 the first AC-AC diesel locomotive AD43C
was received from Alstom, the specification of this locomotive was prepared in MATRAI.
Accordingly it would be more difficult to observe the defects of the cars individually, this was the reason to start developing the first image processing
system to check the wheel profile in motion.
The fist contract was signed in 1998 and the Evaluating Prototype was installed in Rey station near Tehran in 2000.

Hybrid locomotive
The First Evaluating prototype Hybrid locomotiveHybrid locomotive
A hybrid train is a locomotive, railcar or train that uses an onboard rechargeable energy storage system , placed between the power source and the traction transmission system connected to the wheels....
was designed and contracted by railway research center MATRAI in 1999 and the sample was ready in 2000. It was a G12 locomotive that was converted to hybrid by using a 200KW diesel generator and batteries and also was equipped with 2 AC traction motors (out of 4) retrofit in the cover of the DC traction motors. It was inaugurated by missed Dr, Dadman the minister of road and transportation in 2001.
AC Diesel locomotive
The initial diesel locomotive fleet in Iran that was introduced in 1956 was G12 with DC-DC traction system that was replaced with 1971 by GT26CW from Electro-Motive Diesel with 21% AWA (All weather adhesion).In 1992 the GE locomotive was introduced that had AC-DC traction system with 26% AWA and in 2002 the first AC-AC diesel locomotive AD43C
AD43C
The AD43C is a type of mainline 6 axle Co'Co' diesel locomotive designed by Alstom and used by the Islamic Republic of Iran Railways . It was in production from 2000. Delivery started in 2002.-Background:...
was received from Alstom, the specification of this locomotive was prepared in MATRAI.
Wheel View
The trend to increase the weight and length of trains is considerably fast and specially by increasing the cost of energy.Accordingly it would be more difficult to observe the defects of the cars individually, this was the reason to start developing the first image processing
Image processing
In electrical engineering and computer science, image processing is any form of signal processing for which the input is an image, such as a photograph or video frame; the output of image processing may be either an image or, a set of characteristics or parameters related to the image...
