Such spring points are sometimes used for passing loops on single-track 
railways.

There is a mechanism on them to lock them in the wrong position when 
it's necessary for them to be used in the wrong direction.

An important distinction in railway work is between passenger and 
non-passenger working. Some moves which are permissible when trains are 
empty are not allowed when carrying passengers.

I remember an occasion during some out-of-normal working where we were 
all turfed off a train while it was moved to a different platform, while 
we all walked over the footbridge and then got back on it. The guard was 
very apologetic, and explained that it was necessary because it would be 
running over some unclamped points, which is not allowed while carrying 
passengers.

Freight trains have a different set of rules for signalling, and 
sometimes dedicated tracks which are not signalled for passenger use.

How all this information could be shown on a map is not clear.
