What is the standard operating procedure for brakes on SMEE cars in normal conditions?

In normal operating conditions, the standard procedure for brakes on SMEE (Screw Machine Electric Equipment) cars is to use the running release position. This method allows the train to operate smoothly while maintaining efficient control over speed and braking. The running release position is utilized to prepare the brakes for an optimal operation, which permits for regular acceleration and deceleration without the full application of the brakes, thus ensuring that the train runs safely and effectively within the desired speed limits.

Employing the running release position also helps in maintaining the integrity of the braking system by preventing wear and tear that could occur with constant or excessive braking. This management of brake function is essential in the context of operating trains in an efficient and safe manner.

For more context, using emergency brakes only would not be appropriate during normal conditions as this could lead to abrupt stops and potential safety hazards. Applying full service brakes continuously would unnecessarily consume energy and could result in reduced overall brake performance over time. Keeping brakes disengaged is not safe for train operation, as it would mean lacking the ability to effectively slow down or stop when necessary.
