Modern air brake systems use a more sophisticated distributor valve allowing gradual brake release and a faster emergency application. I’m not a driver and stand to be corrected but I would think the operation is a lot more smooth than a vac...

The vacuum brake is about as fail safe as a brake can be unlike an air brake as the triple valve or distributor can fail to operate. It relies on the fact that there are multiple distributors on a train and multiple failure is highly unlikely....

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...
