Can't say I'm impressed - huge trunks of blue cabling coming out of the containers (8 per 4-aspect signal; more if route indicators), unreliable axle counters that can't... um... count, and 3 people controlling a small lump of railway that 2 people used to be able to control - that's progress for you.
Is the camera sitting on a cable drum on the ballast still pointing at the axle counter on P3?
Could have been done with 2 SSIs, maybe 3 if they insisted on axle counters, and lumped under one IECC, one WestCAD, or one MCS without either of the three breaking a sweat - and controlled by one person, with a second person for backup.
But I guess Railtrack spent lots of money "helping" Siemens develop it for the UK market, so they wouldn't want to lose face and abandon it for better systems - last I heard, Portsmouth was going the same way.
Soapbox dismounted, sorry.
