Locomotive class 799 (1:120) TT train

thingiverse

Mechanical locomotive design is a hinged, two lowered and narrowed axles with a central cab for the driver. The perimeter of the hood leads to corridors with recessed steps. The heavily glazed driver's cab with a tropical roof is accessible through side doors. The hinged section has been completely redesigned, with the frame undercarriage with dual wheels remaining intact. Two driving wheels are led by rods with steel inserts, and leaf springs provide suspension. The locomotive is two-source, meaning that the dual wheels are powered by a traction motor that can be fueled either by current from an accumulator or by current generated by a traction alternator driven by a gasoline engine. The combustion engine is a three-cylinder Zetor diesel.
