I'm not sure exactly where the data is derived from, however I know the Southern 377/1s and 377/4s are in the same pool for diagramming so it may be that's what it's indicating rather than necessarily the unit's actual subclass? There are also other exceptions where the fourth digit doesn't...

Yes - it's the drop in bandwidth that's the issue.

There are various workstreams underway that are planning for it and have been for the last year or two - there are still some items of on-train kit that still use 2G, some of which don't yet have solutions. It's actually the removal of 3G that's caused the most pain so far.

The green/yellow one at the bottom left with the warning triangle is from a SouthCentral slamdoor train so would be from around 2001-2005

I've seen this posted on Twitter previously - it shows brown, green and blue versions of the L&SE livery. How legitimate it is, I don't know though. https://x.com/tms1967/status/991742863456301056

My memory is that there was a clash with paths for additional/retimed(?) XC services.

All bar 387201 have been back with Gatwick Express for some time now, probably close to six months.

My understanding is that it was related to how the fleet was originally financed by BR - the odd numbers were financed differently to the even numbers.

They usually use more than one mobile network for this reason. GSM-R is 2G technology so wouldn't have anywhere near the bandwidth.

Southern's HR and training were still based in Southern House until about 2006-ish.

The first ones on the mainline were at Purley Oaks and (I think) Purley, a little over 10 years ago. Selhurst to Streatham Common were done a few years later. I worked on stations around that time and they made a huge difference.

That's Go North-East's offices. The Go-Ahead Group HQ is on Grey Street, Newcastle.

Brighton to Portsmouth Harbour (including Bognor and Littlehampton) and Brighton to Seaford.

In the rules for EC4T charges for units without meters there are factors for this. Can't remember them off the top of my head but it's something like 1.8 times a single unit for two units in multiple.

Most installs will use more than one 4G SIM (4 is typical) across more than one network to try and get round areas of poor reception.
