Yes I'm not too bothered about tours. Easy enough to chuck a unit out on a specific diagram and let people know in advance. For example, the farewell day for the 302s had four of them in traffic all day on a Saturday covering every route. The times were published in RAIL in advance. If I recall correctly, LTS said anyone with a return ticket to Shoeburyness could travel up and down the network as much as they liked all day. The plan worked well, there were loads of enthusiasts. As it turned out, the 302s did one or two peak runs the following week but the Saturday event was still good.
