The arrival of the Brits on the GE must have been like the HSTs on the GWR 25 years later - an absolute revolution in power compared to what they replaced (mainly B1s, B2-3s? and B12s, I suppose?) I suspect the move had an 'electrifying' effect on staff morale - at last the GE was being given some sense of priority vis-a-vis the GN in the pecking order.
They replaced to an extent B12's but they themselves had been replaced by B17's (Gresley - 3 cylinders) B2's (Thompson re-builds of B17 with 2 cylinders) and the B1's (Thompson). There were only 10 B2's and they worked mostly on the 'West Anglia' routes (inc. Royal Train duties).
But yes fantastic to get new investment in what was still very much post war austerity. They were able to realise the twin objectives of heavier loadings and sharper schedules.
Right - thanks. So it still begs the question, why the time-consuming loco change for London-Norwich - a distance of just 114 miles.
As I said before diagrams were varied. I mentioned trains that came in from Yarmouth as 'all shacks' but were then strengthened to go forward express to London and trains with added TC. There was also the summer (Sat only) through TRAIN from Felixstowe (Beach), non-stop Ipswich - Liverpool Street. The summer Saturday service was at times intensive. In 1955, between 12.45pm and 2pm, no less than 7 services departed for London, 4 of which were non-stop from Ipswich.
Reverting to the photo - what was the middle road for - through goods traffic? Was it up only, or bi-directional? (Unlikely, in those days, i'd imagine.) Or perhaps a kind of run-round release road, for terminators?
The original Ipswich station was the other side of the tunnel (before the tunnel was built), opening in 1846. After the tunnel was built a new station opened on the current site in 1860 but with only 1 through platform 'Cambridge style' and a west facing bay. It is shown here in 1883 in the article from Ipswich Star (the 12th picture down):

The original station site was subsequently used for Ipswich MPD (32B) and a wagon repair works. Not sure when the island platform was built but I would guess soon after the 1883 picture.
The centre road was an 'up road' and had a scissors crossover to the 'up platform' approximately in line with the end of the west facing bay. This enabled local trains to terminate in the section at the west end of the platform and through services to still access the London end of the platform. It was also useful when through carriages had to be attached and to release locos.
Other uses of the centre road were for up freight and locos for the MPD, either to be held or to pass a train at the platform (the freights weren't quite so long in those days!). The scissors crossover has long gone, replaced initially IIRC by a single crossover but is now plain line.
The trailing crossover shown in the original picture, near the signal box (the crossover is still there and used sometimes for London-Ipswich terminators to depart to the up line - even though the lines through the tunnel are bi-directional now) was mainly used for loco movements. After coming off a train the released loco either went through the tunnel to the MPD or moved just into the tunnel and returned via the crossover through the down platform road and on to the station yard, where there was a turntable (behind where the Freightliner refuelling point is now).
If the Britannia in the picture had come off the train it is very unlikely to have been in the loco siding. The up starter is off meaning that the train is about to leave or for the B1 to go light engine to the MPD. The Britannia may be there for another service entirely.
The alignment of the station is as stated by
30907.
Felixstowe is due SE of Ipswich but trains leave in the other direction. Derby Road (DBR) is about 1 mile by crow but about 6 miles by rail.
In the picture there is a lot of coaching stock in the yard, perhaps a Sunday? No sign of any DMU'S which means the picture was pre-1958.
Sorry for all the verbosity!!
