Rigid, four-axle tenders are notoriously difficult to keep on the rails and compensating them with conventional rocking beams can be complicated. 
 
Our ‘CSB MiniBlox’ system is easy and straightforward to install and allows all four wheelsets to interact together as they ride over the undulations of the track.
 
The unit is designed for EM/P4 conversions of the Bachmann WD locomotive tender. Brake cross-shaft, pull rods and lever details all included, as well as rear bufferbeam steps. There are also separate guard irons which can be glued onto the proprietary model.
 
It will also fit kit-built tenders where the underside or floor of the tank is flush with the footplate edge - modifications to fit the DJH kit are detailed in the instructions.
