There is one feature that gets my goat even though they are important but the justification/ presentation is a bit iff. Ladles and jellyspoons I give you, the engine shed. Most of the time they are on BLTs where sometimes there was a shed, sometimes there wasn't and the branch would be worked by loco based at the junction or would work to the junction then work the branch (Lambourn comes to mind here). There always seems to be a cat clambouring about on a pile of sleepers or the roof of the mess room. There was a layout in one of the monthlys that had a single road shed when it was a through station with a couple of sidings serving a quarry loader. To me (correct me if i'm wrong) but surely the loco would be needed as it needs to move the individual wagons under the loader and marshall its train. I can see why people add in sheds, they are easily justifiable but its been a little overdone.
