What about a special service for Navy personnel, passenger and/or freight?
Put a pannier on the railtour trio, job done! Truth be told, they'd probably bus personnel from Yeovil. Several pictures of Yeovil Town have Navy Bedford buses in the forecourt - Bedfords, I think they were. This sort of thing:
Freight is a different matter, I have a couple of opens marked down for crates of various kinds: does anyone know the sizes of '60s aero engines?
I've found that using an actual working timetable from the area being modelled can be all you need. For example looking at the FoD branch timetable in the 50's there were sixteen trains a day. If I ever get round to building this layout it will be all I need and is varied enough for me.
Obviously you can add or delete as required, but the bones of a real timetable are pretty useful.
For my Dublingham layout, pinching the Peter Denny timetable resulted in 15 trains per operating session. I generally get through three timetable cycles during a show, operating as fast or slow as I want and it's plenty of excitement.

I remember a bit of a special at Birkenhead school, when we were marched out and stood around the cricket pitch, CCF in best bib & tucker, one came over low, circled and dropped a rope, a load of commandos slid down the rope and “secured the area“ and it landed. When it had cooled down a bit, we were allowed to have a look, we were not allowed in the cockpit, but we could have a look inside. I have a vague recollection they opened the engine doors too. About fifty three years ago…My neighbour,back when I lived with parents in Bebington, flew these for the Forces, three of them appeared over his house one day, very low, circled a bit and continued onwards. No doubt he was waving
