I think there is an issue in heritage railways of reporting and disciplining people. On the one hand people are volunteers and the railway don't want people not to volunteer either The GCR is set up for SPADs due to its unique double track signalling. Lots of movements, but also only 1 single line token. However, due to the double track, general simplicity of the track layout (compared to say Paddington), general good visibility and low speeds, SPADs present a low risk of serious collision. Clearly however, the management mustn't be complacent and efforts must be made to minimise SPADs. Safety leadership is therefore required. I also I think that leadership in a volunteer environment is different from that in a fully professional environment, and presents its own unique challenges.
