An official image (2 of 15) from a internal BR photo album titled 'Refurbished Class 115 DMU Production' shows a set at Marylebone circa February 1978. M51666 has 'Special' on the destination blind, suggesting it may have been here for inspection by HQ staff at 222 Marylebone Road. British Rail.
An official image (3 of 15) from a internal BR photo album titled 'Refurbished Class 115 DMU Production' probably taken at Marylebone circa February 1978. As the chalk on the manifold tells us, this is the No.1 engine on 51666. The two rectangular boxes in the centre under the stepboard contain 'EP' valves, the larger box to the right just before the radiator (with the grille) contains the relays that control the EP valves.

On the left should be M51666 - the dates show the work was completed at the end of January, it looks like it has been in traffic for several weeks before the image was taken. British Rail.
