I assume north to south can be done in passenger service? Yes, off the platform. South to north can be done by detraining, then reversing either via the siding or the main line, then re-entering on the northound platform.

I would have thought you would get a straight green for the normal and the harbour for the reverse.. Whilst I'm not familiar with the area in question; basic signalling principles, as I understand them, dictate that the route with the lowest permitted line speed will always get the junction route indicator. So by definition, the route with a higher permitted line speed will always get the straight green. That was my understanding. I've also heard it said that the route indicator applies to the secondary route, which is usually (but not always) the slower route. Cardiff Queen Street was (is?) a good example of this, where the faster route has the route indicator.

If you scroll north-west to Moor Park the site of another cross-over (long gone) can be seen - trailing, between the fast lines.

The #-over used to be at the north end of the station, controlled by a signal box, as evidenced by this circa 1961 shot showing the wrong-wroad starter SEMPAPHORE. Is that the famous one-time LNER engine "The Blue Mallard"?

What a fascinating photo - I didn't realise that GT3 was used on the GC road.

I would imagine that it was on its way to Marylebone (from Nottingham?), for the BTC bigwigs to see. Rumours abound that it used a Class 5 steam loco frame. The other Vuclan Foundry product that has been on the Met, is of course the EE Type 1, later Class 20.

It is on the down line at Northwood. I don't know where it is going-Nottinghom or maybe Sheffield Vic?

So I guess the engine is not the Blue Mallard

No, it's not. The loco is 'GT3'. I'm not fully conversed with it's history, but I can say that it's gas turbine powered locomotive used in the 60's.

Gas Turbine # 3 after the now-preserved Brown-Boveri # 1, and the Metro-Vick #2 that was converted to an AC electric loco. "Steam Outline" they call it for that type of design. I am not sure if A4s ever normally worked the ex-GCR?

The #-over used to be at the north end of the station, controlled by a signal box, as evidenced by this circa 1961 shot showing the wrong-wroad starter SEMPAPHORE. The photo of GT3 shows the train running on the down/northbound and the photo is taken looking south. The platforms are in fact the old station on what is now the main lines and the new local lines trackbed can be seen on the left of shot. New platforms were provided under the footbridge from where the photo was taken. The crossover can be just seen under the 3rd and 4th coaches and also includes a slip connection to the goods yard, off to the left of shot, the current siding being all that remains of the replacement connection. The only item in view that remains, is the newly built IMR, seen beyond the signal box. The reversal of trains at Northwood is the same now as it was prior to the 1961 resignalling.
