The railway is doing very well on short distance international passenger journeys via the Channel Tunnel, they could do much better on medium distance journeys if they sorted the fare structure out to make it cheaper and thus more competetive with airlines. Also, they should be running through trains from the principalities to further than Paris/Brussels, i.e. Birmingham/Manchester/Liverpool/Glasgow/Edinburgh/Newcastle/York/
Leeds - Italy/Germany/Switzerland/Austria.

There is also huge scope for improved through freight services as they are too slow at present, being held up by protracted customs checks at international borders as well as locomotive changes as there are insufficent multi-voltage loco's to work throughout on each countries' different electrification systems using different voltages. Juggernauts seem to be able to drift through effortlessly although I am not sure what the position is with driver's working hours!

The time was never riper than at present for these changes as the railways are in a prime position to compete with air/road because of the increasing costs in fuel & pollution. It just has to be done, the sooner the better!
