What is the proper position of the brake handle when operating SMEE cars normally over the road?

The proper position of the brake handle when operating SMEE (Standard Metrorail Equipment for Electric Rail) cars normally over the road is running release. In this position, the brake system is disengaged, allowing the train to operate freely while ensuring that the brakes are not inadvertently applied. The running release setting enables smooth acceleration and deceleration, which is essential for safe and efficient train operation.

Using the running release position also ensures that the train can respond quickly to operational conditions without the drag associated with applied brakes. For routine operations where the train is in motion and no stopping is imminent, this is the standard practice to maintain momentum and control.

In contrast, if the brake handle were in the full service position, the brakes would be engaged, causing a gradual stop. The emergency position is meant solely for unforeseen situations where immediate braking is necessary, which is not suitable for normal operations. Lastly, the off position does not provide any brake engagement for safety, which would be inappropriate when the train is in active service. Thus, running release is the appropriate choice for normal operating conditions with SMEE cars.
