(I suppose Chiltern could possibly run a Harrow-on-the-Hill to
Marylebone shuttle if a few non-striking LU signallers could be found
- though are there any crossovers south of HotH?)

There aren't.

I'd like to say 'well in that case they can run two trains in steam'
on each line, but I'm sure there'd be problems with trying to treat
two non-reversible lines as reversible!


There's no access for Down train to the Up Harrow at any point beyond
Marylebone itself, so there'd be no way of running such services with
the main Chiltern route open.

Actually, my mistake, there is a trailing crossover at Neasden, but I
don't think it would help.


Unfortunately, that's on the Marylebone side of the junction and is
almost certainly not signalled from Up trains from the Down Harrow
line.

Oh ang on though, if they used platform 1 at HotH, I think there may
be a crossover. *Not sure if it isn't just a track crossing to/from
the Metropolitan or if it leads to/from the up Chiltern track as well.

I can't remember if this crossover can be used from Up departures from
Platform 1 at Harrow. My memory tells me that there is no signal for
this route. What I can't remember is if the crossover from the NB Fast
to the Platform 1 just passes over the intervening Up line or whether
there is pointwork in the Up line allowing access.
