The different air / vacuum (air pressure in reverse) are compensated by the use of bigger cylinders for a vacuum system so equalising the brake effort. A vacuum brake can be just as effective as an air system although slower acting, hence the...

Vacuum brakes certainly are effective, less complicated and easier to maintain than a two pipe air system although less efficient as the maximum braking force is limited to atmospheric pressure, about 15psi I think. The air brake train pipe is...

Technically fitted with an air pump and combined brake valve for working air braked trains, the engine and tender will still be steam braked. I understand that the air pump will be located out of sight between the frames rather than under the...
