Quick question on this - is the spare unit stored in the "garage" at the end of the Town line platform at Stourbridge Junction?
Also, to swap them, do they have to take one out onto the mainline (well, line next to mainline) to get the second one out and the other back in? Do they also ever rotate them as I realise at the moment, only one set of doors gets used.
Went on 139 002 the other week when doing the LM Day Ranger jobbie - got talking to one of the members of staff briefly as we wondered what the constant beeping noise was - it appears the vigilence alarm goers off every like 10 seconds on these!
Would quite like to take one of these only a flat level mainline and nail it...not that there would be much left of it or the driver by the end of that though!!!
