The queue in such a situation would be jam all the way back to White
City as that is the next nearest turning point. Reversing trains

I don't know if this is an issue on the central line but it does seem
on
some lines that some connects between the running lines have been
removed for no obvious reason , leading to less flexibility in the
service
if theres a screw up. Convent garden on the piccadilly line spings to
mind , not to mention the connection at finsbury park being lost due to
the victoria line using an ex-picc tunnel. So if theres a problem on
the line you get huge sections closed. Doesn't seem like a good
situation.
