It pays to plan ahead! At Guildex Telford in 2019 I had a shopping list and one stand where I spent a few shekels was Skytrex. I have started to put these kits together as many of them go with the Goods Station or the platforms of the passenger station. The white metal and resin castings are easy to clean up and spray prime ready for painting. A couple of mini-kits need assembly which was done with Roket Max, now my firm favourite CA glue.
These two white metal trolleys had some minor flash which was easy to clean and then a light application of a small wire brush in the Dremel and they are ready to prime:
They will be vey useful in transporting the baskets of fruit and veg as well as fish when they arrive from Evesham and Grimsby respectively. The fish, as it happens, came via Banbury with its Eastern Region connection to the GWR rather than from the direct line into central Birmingham. So no Eastern Region B1s were seen delivering the herrings.
The transportation of bananas into Moor Street came via South Wales. My research into an old favourite, the Stratford and Midland Joint Railway, demonstrated that London's bananas took a less direct route from South Wales via Stratford-upon-Avon and Towcester. One way to try to try to make the S&MJR profitable I suppose.
Back to the Skytrex accessories, their web site has good "go-by" pictures as well as the castings in the raw. Very useful. Many models can be purchased ready painted, though, and I have one such example from Telford (because they didn't have an unpainted one!):
