What components do I need for a complete vacuum braking system and how much will it cost?
We are frequently asked what items are required to fit vacuum brakes.
There are of course many different types of locomotives and rolling stock so there is no generic answer.
The example solution shown below is based on a narrow-gauge Romulus hauling two eight wheeled wagons. On the loco, all wheels are braked whilst on the wagons just the rear four-wheel bogie is braked.
