Locomotives
Diesel traction is still by far the most efficient means
of pulling freight. Modern diesel engines return a mechanical
efficiency in excess of 42%, whereas electric traction requires
electricity from the National grid, which after allowing for
generation and transmission losses, is less than 35% efficient.
Translink plans to use diesel locomotives to haul the low-floor
wagon trains. The locomotives themselves will be fully remanufactured
units, fitted with new engines and designed for an operating
speed of 100 kph.
