The service train on Sunday 2 May 2021 was run as a push-pull with the regular Sunday loco No3 and brake second coach No.206.
This was a trial and required the single coach to run with the guard's compartment leading, therefore the double doors were not available for loading milk churns at Horseshoe Cove.
So that meant that an additional van was needed and this was provided by van 101 which was attached to the train at Horseshoe Cove by battery loco No5 which was to provide banking assistance all the way from the Cove up to the terminus at High Topps.
Unfortunately the combined load of vehicles 206 and 101, both of all steel construction, was too heavy and the train stalled at the top of the Greenbanks incline.
So in future the Sunday service will operate with coach 206 carrying the milk in the guard's compartment as usual.
