Also, since the brake pipe is typically used for control and supply of air to the cars, if an engineer is not careful, the air supply can be depleted.

Toyota Motor Corp . said Tuesday it was recalling 397, 263 subcompact and minicar vehicles exported to the United States, Europe and Canada because of improperly designed brake pipes.

Disconnected brake pipes must be stowed on dummy connectors, to allow proper operation of the brakes . ( The picture shows two coupled cars, with a single brake pipe .)

This theory was supported by the fact that investigators who were examining the wrecked shell of train 153944 found the main brake pipe valve, located behind the first car, closed.

When brake pipe continuity exists throughout the train, failure of the brakes to apply or release on one or more cars is an indication that the cars'triple valves are malfunctioning.

This last shuts off the traction motor controls when the air pressure in the brake pipe falls below a preset level, which prevents the train from starting with inoperative brakes.

Since this derailment, CityRail training and operational procedures now emphasise the guard's responsibility to monitor the train's speed, and if necessary, open the emergency brake pipe tap to stop the train.

In 1929, cars 274 and 275 were fitted with additional air brake pipes for use in hauling the horse transport cars between the City and Morphettville Racecourse on the Glenelg line.

This arrangement helps to reduce the above described pressure loss problems, and also reduces the time required for the brakes to release, since the brake pipe only has to recharge itself.
