Newbie here, but with eight years' GR experience. It feels like I have spent much of that time trying to extricate basic factual specifications - such as width, height and total wheelbase - from G manufacturers' material We have a turntable that can just turn an Aristo Mallet (long tender) with about one whisker/ 1mm to spare on each end. The track on the bridge is exactly 1055mm or about 41.5". Its that time of year when you look at your options for Big Locos and one I'm considering is the MTH Triplex (The Challenger is definitely too long). Can somebody who has a Triplex please tell me what the Total Wheelbase is please? Or whether it would fit on my turntable? If not, what other Big Locos would you consider? Another Aristo Mallet? mike in UK
