D7662 was new from Derby Works during November, being delivered to the London Division (D01). This was part of the final batch of locomotives built at Derby after Beyer Peacock failed to complete its intended order after filing bankruptcy. These final eighteen machines were delivered in blue with full yellow ends, although it took Derby Works a little while to get the positioning of the numbers, emblem and warning panel right.

Twelve new Type 2s (D7660 - D7671) were allocated to Willesden to take over the empty coaching stock, parcels and local freight duties in the London area. With the arrival of these locomotives it was possible to release the remaining Class 24s to the Stoke Division, as part of the eradication of steam in the North West. Of this batch of Class 25s D7660 - D7669 were dual braked from new, whilst D7670 & D7671 were not, however these latter two were quickly transferred to the Nottingham Division (D16).

On April 16th D7662 was noted motoring down the LSWR mainline at Wimbledon with a troop special.
