Watching on OTT▸ the rescue loco was 1Z99 which took the sleeper back to Plymouth, then on to Laira.
I'm wondering what the rescue loco would have been? In the past they have used 2 back-to-back HST▸ power cars.
Unfortunately there was no mention of what 1Z99 actually was.
It delayed 1A78 (Penzance - Paddington) leaving Plymouth whilst waiting for 1Z99 to pull into Laira.
Only by 8 or 9 minutes, but looking at
RTT» it was delayed further between Cogload Junction and Athelney Crossing, so now 27 minutes down.
