3 2 Introduction This technical specification establishes the criteria for road/rail shunting vehicles to be primarily used for movements at depots operated by Israel Railways Ltd. (ISR). It is not envisaged that they will be registered as road vehicles. ISR operates a number of coaching stock and freight wagons that cannot move under their own power. All are equipped with standard UIC couplers and buffers. The road/rail shunting vehicle, which shall be powered by a electric diesel engine, shall drive all these types of rolling stock in push-pull operation within the depots and sidings operated by ISR.

4 3 Technical Requirements 3.1 Vehicle concept The road/rail shunting vehicle shall be able to travel on road and rail. It will only be used within the depot confines and therefore will not be registered as a road vehicle The primary function of the road-rail vehicle will be shunting push-pull vehicles around depots, yards and sidings operated by ISR. It is not envisaged that the vehicle will be used on the mainline railway and it will not be used for any other purpose or require any special equipment It is envisaged that the road/rail shunting vehicle is currently in use in similar operations and is as much as possible, a commercial off-the-shelf item The road/rail shunting vehicle shall be suitable for one-man operation The road/rail shunting vehicle shall have bi-directional shunting capabilities, able to drive the trains currently in operations by ISR in push-pull mode The trains (and their configurations) that will be towed by the road/rail shunting vehicle include the following: o double deck push-pull trains o single deck push-pull trains o single deck (first generation) push-pull trains o Electric locomotives, EMU,DEMU o BOBO or EURO locomotive o 3.2 Dimensions All vehicles operating on ISR network, including the road/rail shunting vehicle, shall be operable within the kinematic gauge in Attachment A (A.4) In general, the following dimensions shall apply: Carbody width Overall vehicle length (including buffer) Overall vehicle height above top of rail Rail wheel diameter Height of end coupler above rail Height of buffer above rail < 2'850 mm < mm < 4'680 mm 265 mm 1'040 ± 5 mm ± 5 mm 3.3 Track compatibility The road/rail shunting vehicle shall be capable of traveling around the depots without fully unloading any wheel or the vehicle becoming derailed.
