OJB Ge 4/4 126Langenthal Langenthal

OJB first used transporter cars - that carry a whole 2-axle standard gauge car - then switched to transporter trucks - that each carry one axle of a standard gauge car. The former way used bars to connect loco and tranporter car, the latter uses the normal standard gauge screw-coupler. As the curves on the mettergauge are much tighter the bigger buffers on the loco avoid overbuffering.
