The new diveunder line at Acton will be known as the Acton Relief.  It will have a MU (Multiple Unit) PSR (Permanent Speed Restriction) of 75mph against 80mph on the existing Up Relief.

Thanks, funny thing, I would have had no trouble with the three letter ones.  What one is used to seeing, I suppose. I never heard that one before.

I won't get into the argument whether an HST (High Speed Train) is a DEMU or locomotives operating push/pull  Roll Eyes  Grin

Then we have the Voyagers. Currently DEMUs (Diesel Electric Multiple Unit) but could become EDMUs if they are fitted with a pantograph car.

I'd say HSTs are not DEMU's as they don't work in multiple.

For his golden spanners Roger Ford classifies HSTs (High Speed Train) along with the 91s and mark 4 and Anglias Class 90s.

This fortnight's RAIL magazine (issue 714) has a 32 page supplement titled 'Upgrading London's Railways' which features a section on Crossrail as well as other projects in and around the capital.

A fascinating glimpse, only made available to me because I'm watching the news on iPlayer, so get London news rather than Bristol. I never knew the tunnel boring (really/) machines had toilets on board.

Minutiae apart, as a former miner (for a short time only), I find it especially interesting. It looks much easier to dig through than Cornish granite.
