A 170 page thread is a sign of a forum that is moving forward but it's discussion is diverse (and contains some heated debates)

Isn't it time it was split it up? Should spottings, phottings and days out be separated off (possibly into its own sub forum). Then each service discussion can have its own discussion.

The questions that the above poses, is where does the interesting operational bits go (eg breakdowns, buses on wrong routes).
