They aren't equally spaced, here's a diagram with show the distances in feet, with the gradient and depth, along the line.

The gripper mechanism. A wheel was turned to grip & release smoothly. and a lever released the cable quickly when the train passed over the point where the cable entered the tunnel at Scotland St. It took a good bit of skill & judgement, to operate. The cables ran at a constant 13 MPH, and both were the same length, 11650 yards, any difference due to tunnel length was taken up on the cable drums at the power house.
Strangely enough the original idea was to have all trains spaced along the cable and permanently attached. The cable would then stop & start when the trains were aligned with each station. That idea was turned down by the House of Commons at the Bill stage. You can imagine the problems with slack, and trying to keep the trains in line with the stations. That plan would have also required the stations to be equally spaced.
(Maybe this thread should be merged with the main Subway thread ?)
