69007 Richard Trevithick was to be one of the stars of the Swanage Gala. However it failed on the North London Line earlier on 8th, while working 4O07 04:40 Peterborough North Yd - Eastleigh Works, and was rescued by 66792. The problem is loss of air, and various resources at Eastleigh could not repair it, so 69002 became a replacement for the tour trains, and at the gala. The consolation prize was getting to see it in the sidings at Eastleigh, before it is moved for repair - still present on 9th.
69007 was converted from 56037, which was new from BREL Doncaster in January 1978.
