MG800

As for the station, we as the operators don't tend to mess these things up. Trains and stations would be much tidier if wasn't for the addition of passengers ;D

As for the signal, that will be fixed/replaced under normal maintenance, and no priority will be given to making any signals nice and new or clean under the station refurb - apart from any that have been re-positioned or replaced directly as part of the project.

Of course this particular signal may not be with us much longer depending on exactly how the proposed alterations to the connections to the depot are carried out.

Urgh! IECC You mean it wouldn't be out of place in a SCC - Service Control Centre (except it isn't from there either).

It is after all the busiest 3-sided flat junction in the world, and they don't let just anyone play with it ;D

^{This reply is based on previous sightings of Harsig's avatar and presumes he hasn't changed it recently as it doesn't show up on the work's computer.}

That station does say Harrow on the Hill...

Well spotted tubechallenger! I have been studying that for days, trying to guess the location!!

So we have the island platform at Northwick Park to the extreme left of the diagram and the island platforms at Moor Park to the far right....
But 'hmmm', there seem to be goods yards at Harrow, Pinner, and Northwood. And the old connection from Platform 1 at Harrow to the Uxbridge branch is also visible.

I'm hoping that, if he was asked nicely, Harsig would post a full-size version of that...
PLEASE!! ;D

This photo show a crossover between the fast lines at Moor Park. IIRC that was not there in 1973. When was it installed?

Another thing that puzzles me is the semi's in the diagram are lettered in the 'J' series. Thats something else I can't recall as I thought they used to be in the 'M'' batch.

I am surprised to see that JB45.46.84, JB21.22.77 and JB29.30.99 don't have route indicators, that JB21.22.77 additionally has got a shunt disc for a movement that I can't seem to find at Harrow North, and that there is a second trailing crossover south of the Chiltern island.

Otherwise, this looks wonderful Harsig - where did you get it?

These signals do have route indicators, but they are not shown because the signal is at danger and the route indicator extinguished.

The three routes at signal JB21/22/77 are shown here

No there are not. In the J series the Jubilee currently uses only JD, JE, JG, JL & JM. JD was previously in use at Pinner but became redundant when the yard closed in 1970, JE was used 1961-62 by a temporary cabin at Northwood Hills but was otherwise spare as were JL & JM while JG was in use at Moor Park until the handworked crossover there was removed in 1971. Thus all the J codes used by the Jubilee were available when the relevant sections of the Jubilee were resignalled in the mid 1980s. In fact what happened during this resignalling was that the original M code was retained for the Met signals while J was substituted for M for the jubilee signals, thus Finchley Road had been solely MD became MD/JD. The exception to this rule is Neasden. This was originally MF but became MM/JM. I'm sure that if the code JF had not still been in use at Northwood (as it still is today) then Neasden would have followed the same pattern as all the others and become MF/JF.
