Hybrid locomotive[edit]

The First Evaluating prototype Hybrid locomotive 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[edit]

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 was received from Alstom, the specification of this locomotive was prepared in MATRAI.

Wheel View[edit]

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 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.
