'The Bicycle Belle' used to run on the nearest Sunday to June 21st to take cyclists from the London to Brighton cycle ride back to London and points between. 12 car EPB formations were used (pretty much the only time they were run as 12 car formations for public use), with 6 coaches for passengers and the other six for bikes. These had the seat cushions removed to provide mobile racks, and each of the 6 coaches was for a specific station en route. The long non-stop sections made for some lively running in places - I noted over 80mph on some downhill stretches!
