Diesel traction is still by far the most efficient means
of pulling freight. Modern diesel engines Agen Judi Sbobet 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.
Ultra-flat piggyback low-floor freight wagons would be used
to transport the HGVs. This new type of wagon platform
has been developed jointly by Hupac S.A and the Swiss Federal
Railways, especially for use through the Gotthard Tunnel.
Designed to transport 45 tonne HGVs, the low floor arrangement
is such that the Woodhead tunnel could accommodate the largest
lorries in twin-track configuration.
