To get the line open ASAP, they didnt bother with moving block
sections or ATO, instead just having the same signalling system, but
as a fixed block with Train Stops.

And the system is so sparse that train capacity is restricted to far
below what the stations can easily handle - each station has basically
one home signal (with a VERY high speed overlap) and one starter
signal (with a low/medium speed overlap). As a result, run-in/run-out
capacity on the JLE is severely restricted, as the distance between
block sections is so much higher than one of the older, more
thoroughly signalled lines.

Once the new moving block system comes into its own, the absolute
capacity of the line will increase significantly, as long as dwell
times are kept as low as possible.
