This is my 6 stud wide model of GWR 3200 class (dukedog) they were designed by collett for passenger train work. they were constructed by using the frames from a 3300 class bulldog and the boiler from a 3252 class (duke) as they utilized double they an anachronism from the start but nevertheless very lively little engines and most had long working lives one expample 9017 has been preserved.
About this creation
here you can see the boiler design very well
this loco uses standard lego train parts as i dont have any wheels from BBB (big ben bricks) but they are hidden by the double frames
