Southern class 377.

How many different sub-classes are there of these units, and what are the main differences between them?

AFAIAA:

377/1 and 377/4 are 4-car DC only. They are technically identical but one batch has 3+2 seating in the outer (driving) cars and 2+2 in the inner and the other batch is the other way round (I can never tall which is which!)

377/2 and 377/5 are 4-car dual voltage and are technically identical; not sure about seating arrangements. At present, 377/5 all work on Southeastern on the Maidstone East line.

377/3 are 3-car DC only
377/6 are 5-car DC only
377/7 are 5-car dual voltage.

Also I think 377/4 have a partition between first and standard but the 377/1 do not. 377101-120 are 2+2 througout, unlike the later 377/1 which are as you describe. Originally 377121-164 were allocated to Selhurst and normally only did metro work alongside the 455s. A few years ago the two fleets were combined so they all turn up anywhere.

The major difference between /1 and /4 was the seat covers on /1 were a dark
coloured velour (the same as /3). The /1 and /3 luggage racks are solid
glass rather than plastic. All sub-classes been refurbished to have the same
seat coverings and colour scheme. /2 and /4 tend to have a glass partition
(no door) in the middle of the end carriages and a partition with a door
between standard and first classes.

The seating arrangments are one of:
- 2+2 throughout (some /1 and all /3 as built (but this may have been
changed).
- 2+2 end-cars, 3+2 inner cars - I think all /2 and /4 follow this pattern.
- 2+2 and 2+3 in all cars, the 2+2 seating is at the ends of each car with
2+3 between each set of doors.

It's more complex than that with 377/1 and 377/4: 377/1s have three different configurations:
377101 - 377119 are 2+2 throughout (unless this changed when refurbed)
377120 - 377139 are 3+2 in the outer cars
377140 - 377164 are 3+2 in the inner cars

All 377/1 and 377401 - 3774xx have no first class partition doors, these being delivered for the last couple of dozen or so (I will try to confirm numbers later).

Another difference which I have experienced, but can't remember which
subtype is involved, is that some units do not have luggage stacks by
the doors. The overhead racks are not deep enough to take a large
suitcase, so the luggage stacks can be very useful.
