[PLUMB LOCO]

It's in reference to the third-world single line track system, still in use in a lot of the country. Having to wait for trains to arrive before leaving because of the track layout, is a joke. It belongs in the flintstone age or third-world countries, not in a EU country where so much money has been invested in the railway system.

You wouldn't tolerate a single lane motorway, so why tolerate a single lane track?

There are many thousands of miles of single track railways throughout Western Europe and they operate successfully - it's called operating to a timetable - novel idea??. The idea of doubling the DSER is nonsense and shows that you have little appreciation of the terrain through which the line runs, the costs associated with such a massive proposal and the return on same - we not talking a few packs of Hornby track!
