The first 5700 locomotive, No . 7711, underwent trials from January to April 1956, first running between tripcock brake valves after problems were found when running in reverse.

In EP operation, a distributor, performing functions similar to those of the triple valve, is operated directly and instantly by electrical control from the driver s brake valve.

When the driver wishes to make a brake application, he operates the driver s brake valve which releases some air from the train pipe, so operating the triple valves.

If the electrical system failed, the driver merely had to move the brake valve to a further position and the same valve operated the fail-safe Westinghouse system on the train.
15.
Steam is supplied to the steam brake cylinders from the locomotive boiler via a valve ( the brake valve ) which may have several fixed settings or be infinitely variable.
16.
There was a single driving position at one end of the locomotive with the power controller on one side and the Westinghouse air-brake valve and hand-brake column on the other.
17.
If the short end were to lead, then the driver would have had the speedo and brake valves behind him, and he may not have been able to properly see all signals.
18.
As well as the wheelchair compartment, which has tip-up seats, each will have a guard's compartment with ( emergency ) brake valve, vacuum gauge, side ducket lookouts and a standard seating compartment.

The train could be stopped faster if it were running engine first because the driver could use the brake valve in the engine instead of the somewhat less effective brake valve in the autocoach.
