I am currently planning my next layout and want to include a couple of freight trains where the wagons and freight would be appropriate for the early sectorisation period. I will not be able to accommodate long trains as my space is very limited so would like something that would have normally had just a few wagons, somewhere in the region of 4 or 5. I have already decided that a nuclear flask train (loco, barrier wagon, nuclear flask wagon, barrier wagon, brake wagon) would fit this criteria but wonder if any of you can suggest other possibilities for suitable wagon types.
