The TCDD had a lot of 3-coupled tank engines over the years (some ancient designs and some very modern). I find them to be extremely cute engines and I picked up a Fleischmann class 89 and converted it into a TCDD 334X tank. The TCDD never had this particular engine, but if it had it would have looked right at home and fit into the 334X number series.
