Colas livered 56113 and 56087 tow three track machines through
Roade Cutting. An unusual working running as the 6Z56 14.17 Bletchley to Guide Bridge involved the movement of DR73906, DR73907 and DR73910. It's good to see that these class 56s still have a useful role to play on the modern railway. Despite their far from good introduction they have matured into good machines.
