Last Night on the Victoria line

Sutent

I was stuck on the Victoria line for ages last night around 1900. Had to eventually get the 91 bus home. There was<span style="font-family: Verdana, Arial; font-size: 13.2px; line-height: 15.84px; background-color: rgb(255, 255, 255);"> a defective train at Oxford Circus on the Southbound. The station quickly became overcrowded and closed. Sensitive door activation, followed by someone taken ill, then multiple passenger alarms operated. Then no forward movement. Train shut down and opened twice, only Restricted  mode RM was available so it limped to Victoria sidings to stable. Not a good service by any stretch!</span><div><span style="font-family: Verdana, Arial; font-size: 13.2px; line-height: 15.84px; background-color: rgb(255, 255, 255);"><br></span></div><div><span style="font-family: Verdana, Arial; font-size: 13.2px; line-height: 15.84px; background-color: rgb(255, 255, 255);">For those of you who don't know what RM mode is: </span><span style="box-sizing: inherit; border: 0px; font-family: 'Open Sans', sans-serif; font-size: 15px; font-weight: 700; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; color: rgb(51, 51, 51); line-height: 24px; background-color: rgb(255, 255, 255);">RM mode</span><span style="color: rgb(51, 51, 51); font-family: 'Open Sans', sans-serif; font-size: 15px; line-height: 24px; background-color: rgb(255, 255, 255);"> allows a train operator to operate free of the ATP system, all speed pairs are ignored and the driver can drive past signals in the “stop” aspect. However, RM mode cuts the motors off when exceeding 16km/h, and automatically stops the train when exceeding 18km/h.</span></div>

Sorry Automatic train protection mode (ATP) is as follows:<div><br></div><div><span style="box-sizing: inherit; border: 0px; font-family: 'Open Sans', sans-serif; font-size: 15px; font-weight: 700; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; color: rgb(51, 51, 51); line-height: 24px; background-color: rgb(255, 255, 255);">ATP</span><span style="color: rgb(51, 51, 51); font-family: 'Open Sans', sans-serif; font-size: 15px; line-height: 24px; background-color: rgb(255, 255, 255);"> basically assigns each train a speed limit. This speed limit takes into account various factors, including but not limited to track conditions (slower in a curve), distance from the train ahead and any other obstructions, and half-height platform screen doors state. In theory, when a train is too close to the preceding train, it is automatically assigned a lower speed limit – the lesser the distance the lower – down to a “0/0” speed pair, which basically means “STOP AND APPLY BRAKES”, telling the train to stop.  </span><br></div><div><br></div>
