No- Strictly static. I'm not thinking of "toys", but display pieces. At present I am buying brass assys made by CCM, at considerable price, but they are appropriate only for the Kibri 934. The Herpa models are fine -except for the track assys which look undersize, at least according to photos of their prototypes I have seen. The "rubber band" approach used by the manufacturers -in my humble opinion- cheapen the look of the final model. I have tried the individual links by another supplier, but they do not fit over the wheels of the side-frames, and are devilishly difficult to handle. I'm thinking of a one-piece unified "casting" of just the tracks themselves or of the entire sideframes.
Thanks for your consideration
