You are most probably correct. East Midlands Trains was founded in 2007, and in 2013 I still saw an ex-central trains class 153, and this was 6 years after East Midlands trains was formed. Chances are there may even be the odd ex-central trains DMU around now.

It does look like the right width.  Presumably you have to be very accurate with your track laying first (and only?) time.  Best of luck with the rest of the layout construction.

Yes, once it's stuck, it's stuck for good! It's not too hard, just put the tape down where you need it to be, and lay the track on top of it. Just try to centre the piece of track, and push it down with a light amount of force. When connecting two pieces of track, just slip the rails/fishplates together (keeping the track off of the tape) then when you think you have just about centred the track/straightened it, place it on the tape and push lightly again. Really handy method!
