German Railway’s Stuttgart works has produced a range of small retention tank emptying vehicles using pumped collection tanks from Sanivac.
The battery-powered carts are small enough for convenient use at stations or carriage depots. The batteries power built-in pumps to transfer waste from the train’s tanks into a transfer tank on the vehicle. Headlights provide adequate working illumination, regardless of trackside floodlighting.
Tank emptying is achieved by simply reversing the pump direction to discharge through the connection hose. If a waste disposal drain is convenient to the on-board tank, the pump unit can be used to empty effluent directly.
