I was watching a video ("London Underground - Sparks and Steam" by TVP).
One piece shows Jubilee 45709 coming into Amersham from Aylesbury. It is uncoupled and moved to a siding and electric locomotive #5 John Hampden connects and takes off with the train into the city.
Just before 45709 is uncoupled, a trainman climbs around front and moves a lamp from a bracket at foot level from the front right corner (left if looking straight on at it) to the a bracket in the center.
I have found info on BR steam head codes and a lot of info about tube/subsurface electric light head codes (including the DD Forum, of course). I can probably assume the lantern in the lower center means light engine. However what does the first position I mentioned mean - passenger train? Several of the references I found say various things but none seem to apply. Any help greatly appreciated.

As far as I know the standard BR steam head codes would have been used by steam locomotives running on the north end of the Met. Having watched the clip you are referring to, the jubilee is seen arriving with an 'A' (express passenger) head code (two lamps - bottom left and bottom right) In the next shot where the head code is being changed, the shot starts after the locoman has come round the front of the locomotive and as far as I can see one lamp has already been removed. The other is then repositioned in the centre to give a 'G' (light engine) head code. www.uksteam.info/gwr/hcodes.htm

Interesting - normal LT (Met) trains were were worked by 2-6-4T locos (whichever variety Neasden had) north of Rickmansworth - the loco change point wasn't moved to Amersham - and I would have expected them to be class B (or 2) - ordinary passenger train. So presumably a special of some sort (is it LT or BR coaches?) Ah! The London Transport Metropolitan Centenary Rail Tour (clicky), 26 May 1963 (One wonders what the possibility of a recreation 50 years (to the day) later is!)

They look like Dreadnoughts.

Thanks all - especially Harsig, as usual - now it is all clear to me. I missed the other lower lamp on arrival.
So, another question: is the lamp position reference of left/right done from a head-on view? (I would think so).

I've always understood it to be the view as the train approaches. A quik Google gives this link though unfortunately it has come from *that* railway company.

Yes, it is the view from the front, the view of the person who has to see them the signalman.

I may have something up my sleeve, once I've got rid of this manflu.... I know which Sectional Appendix it is in, but I don't think I can stand for long enough to find it.
