Were grounded (railway) van bodies used in Germany in the same way as they are in the UK, Tim? Perhaps a further use for an older model...

There is a V36 (what else) lurking in the cupboard, it is the Roco version, I am not a huge fan of Roco but do like their more simple locos.You could always have something larger such as a radio controlled Br 290 or Br 360 if modelling towards the end of DB (1989).
Use small zip ties instead and daisy-chain them until you get the length required. You can adjust them up quite tightly to hold parts quite firmly. You have to cut the daisy chain to remove any part, and use a new tie to replace, but they are cheap enough.Tidy.
Watch those rubber bands. They have a habit of perishing remarkably quickly.
