My train had to use a different platform at margate the morning due to the normal one being occupied by a train composed of a rake of 5-6 yellow, older style carriages with a GB Railfreight diesel loco on each end. There were very bright spotlights underneath the carriages pointing outwards.

What would this train be used for?

It's one of a number of measurement trains which are used to examine the track. One of them is a yellow HST. Google 'measurement train' for more info than I can possibly furnish you with.

ETA: Tonker beat me to it.

It's a measurement train.

It checks for defects in the rails using lasers.

We own and operate a fleet of 11? I think? Measurement trains.

Most of the coaches are barrier vehicles, the measurement systems will be on the centre/two coaches.

They measure alot of different channels, there are a few vids on youtube.

Are they lasers, or "lasers"?

Being GB stock, most definitely they're "lasers". [DRS] Probably planting IED's to deter other operators from getting the contract [/DRS]

However it's spelt, it's the new Peasant Reduction Programme getting underway.

That bad boy trundles past our house twice a night. It really is quite long!

I saw that NMT at Wolves once while sat there waiting for mine. The diesel locomotive (one with the squashed nose like a bulldog) made such an incredible noise pulling out!

Looks like it's delivering Chuck Norris's new breakfast cereal dispenser.

Not sure but, I suspect that long train of yellow wagons headed by a Class 60 Diesel is loaded with ballast rocks. Looks like one used to lay fresh ballast during track laying or renewal. Those different wagons in the middle may be tamper equipment which settle the fresh ballast by tamping pressure and vibration.

One or two TV programmes recently about the railway showed operations like that including replacing a big road bridge overnight.

Whatever it is, I can tell you that when it trundles past the window of your flat at 1 am, bleeping and vibrating with lights shining, it can easily be mistaken for something out of the war of the worlds.

That is a serious bit of kit.

I'm always in awe of the work those big machines can do.
Walking down by the canal yesterday I was thinking about how they were all cut and shovelled by hand.

It's one of mine. Off work at min but unlikely to be NMT. Being the South East it'll be TRC (Track Recording Coach).

Similar to NMT but less tech, slower and doesn't usually have the PLPR marshalled.

I used to look after HOBC stuff, that was interesting but also a total pita as too many different interests involved. It's planned to come 'in house' so hopefully that should ease things somewhat.

System 4 High Output Ballast Cleaner - HOBC

Designed to replace the ballast under the rails without a full renewal taking place. Much less intrusive, allows for the adjacent line to be kept open for train running, work can be done overnight vice taking an entire weekend, less manpower, safer, more productive etc etc.

One end of that train will be empty 60T wagons, in the middle will be the cleaner and the back end will be freshly loaded ballast from the Local centre/quarry. The wagons are called MFS and each set of wagons will have a conveyor belt system running between them.

The machine takes up the old ballast, cleans what it can and returns it to the ground. What it can't return goes into the empties and eventually onward for recycling. the void that's left is filled with the fresh stuff from the quarry.
Following that the track is realigned using a tamper (bit like a full geo).

Much more to it than that but should give you an idea of what it's about.

Picture paints a thousand words so a video is even better.

haha yes point taken, but down this corner of the country normally I only really see 4 car EMU sets and the odd Javelin so 6 carriages and two diesel locos stood at a station is quite an impressive sight!
