L423 (51361, 59513 & 51399) runs along the down relief line at Waltham St Lawrence on 5 March 1988 with the 2F33 10:49 Paddington to Reading Network SouthEast service. Disappearing into the distance is 47376 with a short engineer's train. Network SouthEast did not immediately apply their new livery to the entire Class 117 fleet, instead most units just received small stickers on the cab front, and the sides of each vehicle. L423's turn to finally be painted into the red, white and blue colour scheme came the following year.
