The workings scheduled with 455/456's are timetabled about 14 minutes to get to Norwood Junction from London Bridge. The same workings with 377's are scheduled to take about 11 mins. I always thought the line from Forest Hill to New Cross Gate was steep- southbounds trains (particularly 455/456's) always seem to get faster as they approach Sydenham. If you stand on the platforms at NXG and look south, you can really see a very pronounced climb, so not surprised they struggle! I was doing a topographic study of the South London area with some GIS, to do with flooding if the sea level and the River Thames rose. The whole Forest Hill/Brockley/New Cross area is greatly raised from the surrounding area by several metres in elevation - even when sea levels rose to the maximum level the model would allow they weren't hitting Brockley and Forest Hill. It's noticable when you take the P4 or 122 from Lewisham to Brockley, because it's essentially an upward incline for most of the route! I see "fast" 455s running past the morning Electrostar I'm on between Forest Hill and Whitechapel on the Overground, and when they're going northbound we end up almost going at the same speed as them when we're on the "slow" line. The Overground trains will have 5th car inserted. Going northbound and up the main drag between Brockley and Honor Oak Park, I reckon a 455/456 would struggle to exceed 45 mph. Even from a standing start a 378 can touch at least 55 mph up the hill before braking for the next stop. They are even quicker on AC power (north London line) but max speed there is 45.

They could substantially lengthen trains but in certain cases that would mean platform lengthening - Honor Oak/Brockley etc. can take 10 car trains, but Canada Water wouldn't take more than four, for example

Southern have begun to do mini-refurbs on the 455's. New flooring, new handrails above the doorways, and a lick of paint inside and out. They do look good, but I feel a certain amount of turd polishing going on! Having said that, at least Southern are polishing their turds, unlike certain other TOC's

But I'm glad they are, even though they don't really need it. Love how Southern look after their trains- if only other TOCs would take a leaf out of their book.

Meanwhile, Southeastern's Electrostars look a state, as do some of their Networkers - which is a shame, because Networkers are my favourite train type.

Those Networkers are a heap of sh*te. Not because there's anything fundamentally bad about them, just Southeastern don't seem to give a flying f- about anything I'd love to see Southern get hold of them and work some of their magic on them

The Networkers would be great trains if they were looked after properly - nice, simple comfortable trains for suburban work.

A nice little touch was added to displays on South London Line Stations last night, that said "Farewell to the South London Line, after 103 years and 1 week of service. Bon Voyage". A nice touch by Southern i think.

More info on new class 377/6 (source Modern Railways magazine March 2013)
unit numbers 377601-634 (34 units x 5 car) power 2000 Kw with 8 motored axles (4 car 377 are 1500 kw and 6 motored axles) so more power per car body uses latest version for crash worthiness (like the 30 West Anglia class 379 units) seating (no first class) is all 2+2 toilets 2 (1 disabled, one normal smaller) intended use : from December 2013 on Suburban routes via Sutton, Hackbridge and Gypsy Hill thus allowing more suburban routes to become 10-car
Once delivered there will be 962 class 377 cars 377101-164 (64 x 4car) 377201-215 (15 x 4car) 377301-328 (28 x 3car) 377401-475 (75 x 4car) 377501-523 (23 x 4car) 377601-634 (34 x 5car)
I think the order is technically 122 extra cars for growth and 48 to replace the 456s which are moving to South West trains). SWT will use the 2xcar 456s to lengthen trains to 10 car (they can couple to 455s)

SWT will use the 2xcar 456s to lengthen trains to 10 car (they can couple to 455s) I think in practice the 5 car 377/6s will be similar in performance to the 376s in use on Southeastern. Thinking about it they might be a bit slower accelerating as they are geared for 100 mph rather than the 75 mph of the 376.

Thinking about it they might be a bit slower accelerating as they are geared for 100 mph rather than the 75 mph of the 376. Not sure how much the gearing will change it with modern powerful motors. Initial acceleration will probably be better for the 75mph geared trains, but probably not much in it after about 20-30mph. Having now checked 2000kw =400kw/car is about 536hp/car, which is more than double the 250hp/car on a 455 or 456 Shouldn't be any problems accelerating up hills. A 10-car 455/456 would have 10 motored axles compared to 16 on a 377/6

Nice! Is there yet a date when they'll enter service? I know that they need to be in service by December, in time for the timetable changes.
