The NG10, being USA built, has a few quirks compared with the primarily European built locos used on the narrow gauge. One of these is the fitment of the running boards to the loco. On most engines these are mounted to the frames but on the NG10 they are attached directly to the boiler via large brackets. As the boiler is effectively new identifying the correct mounting points has been quite a task as our set of original drawings for the NG10 does not clearly cover this. However with the help of the many photographs we have of no 61 in service the problem has been overcome as our pictures show.
