How does the loco know when the rear of the train has passed the point that the driver pressed the button? Is it something that drivers use frequently? Thanks.
Pressed what button? Don’t understand the question here.
Several systems available, length is programmed in before starting (often in feet as they are US systems) and there is also a countdown read out on screen. Most locos have 2 speed measurement methods these days (wheel rotation and ground speed radar) but not sure which is used.Sorry question was very poor. On certain locos there is a train length button that can be pressed by the driver at for example the start of a speed limit... It will then play an audible warning when the rear of the train has passed that same point allowing them to increase their speed. Just curious as to how it works. GPS? Train length programmed in somewhere?
Where is the information from the Tops sheet entered? On newer locos I would assume train management screens but on something older like a Class 57? Thanks.
Yes a Train Length Button is correct. The driver enters the train length off the TOPS sheet, train consist, I think 5-10% is automatically added for the total length.
When the driver reaches the termination of a specific speed to be able to accelerate, they press the button, it counts down in feet and bleeps once the rear of the freight train is clear.
