I caught the 20:59 from Birmingham New St to Worcester Foregate St last night (Wed May 30). Normally this one goes through to Hereford, but last night it only went as far as Foregate St. The
LM▸ conductor was very diligent about announcing this, about why (emergency engineering works) and the arrangements for beyond-Worcester passengers (cross to the other platform at Foregate St and carry on on the
FGW▸ train to Hereford). I assume that they were letting the FGW one run through because it then runs empty from Hereford via Abergavenny back to Bristol, whereas the LM one would want to run back to Worcester at a time when they wanted to close the line.
There had been complications in the morning too. I'd caught the 09:31 out of Foregate St. Normally this runs to New St via Shrub Hill, but there was a signalling failure and we passengers ended up having to swap to the other platform (see note) - which meant that it never went to Shrub Hill.
Can any of the industry insiders fill in the detail of what went wrong? Our old-fashioned semaphore signals may be labour-intensive but they're usually very reliable.
Footnote (for the benefit of readers who haven't been to Foregate St - see also
http://en.wikipedia.org/wiki/Worcester_Foregate_Street_railway_station)
Foregate St has two tracks and two platforms and looks like an ordinary two-track station. But they're actually two separate single lines and trains travel in both directions over both lines. Platform 1 on the south side serves the line from Shrub Hill while platform 2 serves the direct line from Droitwich. Both lines continue westwards as single tracks over the river bridge and eventually get sorted out into conventional double track at Henwick (where there's a signal box and a level crossing).
All this was done back in the 1970s so as to save a signal box at the junction between the Shrub Hill and Droitwich lines at Rainbow Hill, to the east of the station.
Meanwhile, the station is up on a viaduct, so there's 40-odd steps up to each of the platforms. Which means that swapping between platforms is not the easiest thing to do. We do have lifts to platform level, but that's not very useful when you have to transfer a whole trainload of passengers. If you're travelling west, then you're better off changing at Great Malvern (if you can), because it'll be the same platform.
