Transport Design International (TDI) and Severn Lamb Transportation have constructed a standard-gauge light railcar, which has been under test at Long Marston in Warwickshire (UK). It is intended as the first of a new generation of vehicles and comprises a bi-directional, 18m-long diesel-electric railcar with 66 fixed seats and an overall carrying capacity of 120 passengers. It is capable of operating at speeds of up to 65km/h (40mph). The vehicle has been ordered by Konya Șeker, a food processing company located in central Turkey.
The railcar has been designed by TDI and constructed by Severn Lamb with a view to developing a niche product that can be configured either as a single or bi-directional vehicle. Internal layouts and aesthetics can be varied. All vehicles are DDA/RVAR compliant.
The first unit uses a 135kVA diesel generator to power electric bogies, but vehicles can be fuelled in different ways including LPG or bio-ethanol. There is an option for an advanced series hybrid, involving fuel cells and lithium-ion batteries.
