On 1 September 1955, 60700 had just departed from Peterborough when the front bogie frame broke. The locomotive derailed at a speed of 20 miles per hour (32 km/h) at Westwood Junction. It was recovered and repaired.
The loco had many nicknames:
Hush Hush (This is because the project was a secret)
Galloping Sausage (as a result of its boiler shape)
Plans in 1929 to name the original engine British Enterprise were dropped, although nameplates had already been cast; a 1951 plan to name the rebuilt engine Pegasus did not come to fruition either.
