Royston station is fully bidirectional, but only the station. A relic of
the King's Cross suburban electrification when the service forward to
Cambridge became a diesel shuttle.


Isn't that true of Worcester Foregate Street as well?


Well yes, but it's not quite the same thing. Royston station is fully
bidirectional, whereas Worcester Foregate Street has one platform that can
only be accessed to/from Worcester Shrub Hill and another that can only be
used by trains avoiding Shrub Hill. Glenrothes with Thornton station, in
Fife, is similar.


As is Navigation Road (Altrincham) *one platform for the Metrolink and one
for the Northern *Chester-Stockport-Manchester service. *Both bi-directional.

Bare Lane near Morecambe seems to be as well. *Trains that go to Heysham
have to use one side of it in both directions.



Indeed it is - been that way since the present Morecambe station was
opened in 1994. Two independent (i.e unconnected) single lines from
Bare Lane to Morecambe - up & down Morecambe (runs to platform 1 at
Morecambe and uses the old eastbound platform at Bare Lane both ways)
and up & down Heysham (platform 2 and the former westbound platform).
Former is OTW without staff, latter is staff worked as it has the keys
for the ground frames for the Heysham branch at Morecambe and the
Heysham power station siding attached to it. It used to be double
from Bare Lane to Morecambe Promenade, but the method of working
changed when the latter was closed (and it's platforms built over -
the old station building still stands and is used as a pub and
restaurant). The few trains that go to Heysham (currently the 10.19
SuX Leeds to Heysham Port & 13.15 return passenger service plus the
weekly DRS nuke flasks from Sellafield) must use the up & down Heysham
line and platform 2 at Morecambe - the train crew operate the junction
ground frame there to get onto the branch after reversing at the
platform. The set up allows two trains to be on the branch at one time
(i.e a unit can shuttle to Morecambe & back whilst another is down at
Heysham or there can be two trains at Morecambe), so it allows a
certain degree of operating flexibility.
