moretrains_gondola provides gondola wagons carrying a variety of loads. So far empty, cobblestone, mese, rails and toilet paper options are available.
The gondola wagons are all constructed the same way, with low wooden sides, steel chassis and buffers. The sharp curves of advtrains mean that visually the wagons appear to suffer from 'buffer locking', which is where the buffers of one wagon collide with another wagon's buffers when leaving a sharp bend.
