PJLW 'Mamod' Vertical Boiler Loco

This PJLW engine build dates from 2018 and is a proper Mamod Vertical Boiler loco! It uses the Mamod VB Marine boiler and gas burner. The loco is very similar to the twin oscillator VB loco made by PPS/RWM. The loco uses a Mamod marine boiler that makes plenty of steam. The loco is very controllable with the Mamod SL 'reverser' valve fully open and the steam regulated using the boiler needle valve.  In the end, this turned out to be quite an expensive way to build a VB loco but I am very happy with the result!
