Re: Really?

On the tube, or are you just pissed with the RMT over the Southern thing? Because the way I see it

(1) effective management doesn't antagonise the staff to the point of dispute

(2) driver only operation is not as safe as two-person operation (where both of the roles carry a safety responsibility)

(3) drivers operated doors are not as safe during train dispatch as guard operated doors are (and the RAIB agree - "[...] trains operated by Southern [...] are equipped with external CCTV cameras which cover the area along the sides of the train, and provide images which are displayed in the cab. These images are suppressed once the train has begun to move. It is important that the driver is not distracted from observing signals and the line ahead during departure from stations." The images for most of these systems are not recorded and many have a lag of 0.5-1.5 seconds - presumably due to compression required to send them over the air to the monitors in the cab. Some images are displayed on screens on the platform, which can be affected by dirt and sunlight and which pass out of the driver's line of sight within moments.)

(4) anyone who says "well, the tube has been DOO for years" has missed the fact that stations are categorised as A or B type depending on the amount of curvature / amount of platform that can be seen from the cab, and class 'B' stations require a member of staff on the platform to assist with train dispatch - though the ultimate responsibility for starting the train is that of the driver. Even class 'A' stations have SATS (Station Assistant, Train Services) - they hold the baton up to signal that they think it's safe to depart. In the end, the tube is quite a controlled environment compared to the mainline.
