On June 13th 1998 I was on the Slug and Slog railtour and 73131 front bogie derailed in Bescot Yard and wthetourwas taken forward by 58028!
That is sorta partially correct !!!
I was the TCS on duty and the Rugby conductor driver and Hither Green drivers arrived separately. I sent them over to the down receptions where the pair of 73s were stabled - their intention being to run down the receptions towards Tame Bridge, then set back onto the train on the UDGL once the pair of RfD 47s had departed to Saltley. The train arrived from the north onto the UDGL and ran down towards Tame Bridge.
The signalman in the Down Tower called me and his opening line was "You are never gonna believe this" !!! Basically, the drivers were taking the locos down the receptions when the leading wheelset of 73131 left the rails. My immediate response was to find the most suitable blue star loco to multi to the remaining 73, and get rid of the train PDQ.
I called the "boss" at Crewe and asked if 37675 would be the most suitable replacement to go with 73128 (I think it was). and sent drivers out to do moves. The 73s were split and the remaining 73 was sent up the north end of the yard, the crossed over and run to the south end via the upside. 37675 was fired up on the holding sidings and brought off the holding siding ready to back up on the train, with 73128 coupling onto it to lead via Aston.
It then became clear that the derailed 73131 was locking up all the track circuits on the receptions and preventing the fresh power from reengining the train. I got another driver to go over to the holding sidings and fire up 58028 and drop this onto the north end of the train, so it could be hauled up to the north end. so that the locos could be dropped onto the train via the "middle".
IIRC we got the train away from Bescot a smidge over 60 mins late which was pretty good in the circumstances.
So yes, 58028 moved the train within the yard complex but 37675 was the loco that replaced the derailed ED.
