In fact DJH still produces 3 versions of Garatt (one is available both in Ho and HOm) - if you choose to select the biggest one - remember to order a second engine to go with the kit, or otherwise it will be too slow (you will need to have a truly large railroad to accomodate it anyway, as it requires quite a big radius to turn (my guess - about 3 meters). The smaller ones are good because they allow for more colorful paint schemes, while the big one can only be black. The model is abou 50cm long when finished and requires lots of skills cause naturally it only should be welded to hold.
