I'm interested as to why you think loco's would come from a european manufacturer Burkitt. Apart from the 67's being built in Spain with GM bits and the romanian 56's have any locos ever been built and designed by a european manufacturer? I still think that the 70 may be the last ever new diesel, (but maybe we'll see another batch for DRS or someone,) after all which bank will put up the money for an oil burner with a 30 year life when oil reserves are due to run out in its life time in addition to the PR problem of emissions during climate change. Who knows what financial penalties future governments will impose on emissions?
