MTH Premier Big Boy (UPGRADED TO 3v Proto 2)


This beautiful (AND MASSIVE) MTH Premier Big Boy started life as a PS1 model and was converted to 3v Proto 2 allowing for DCS control.  Fully tested, freshly serviced, and in perfect running order, this piece is a site to see coming around your layout.

THIS MODEL WILL ONLY RUN ON O-72 AND LARGER.  Please understand that this is not a suggestion and that it will derail if run on a smaller radius.  Because of the size and weight, it prefers to run on a hard surface and not ideally made to run on carpets.
