47462 passes Marshfield on 28 April 1984 with the 10:16 Cardiff to Paddington relief. However, all is not well here, as the train is being pushed from the rear by 37251. 47462 had shut down approximately a mile up the line, and after a short delay, the 37 was summoned from Cardiff to push the errant train to Newport, where it was terminated. Not a very good performance, failing just a few miles out, and then having to get pushed to the next station! Of course in 1984 there were plenty of spare locomotives available, and as they were all owned by one company, there was no problem in just using the nearest suitable one to quickly clear the line.
