GTRM - a joint venture of GEC Alsthom and Tarmac acquired the Central Infrastructure Maintenance Company in 1996. It purchased a few new machines, and in 2001 took over Centrac's fleet of old machines. Their livery was yellow with maroon cabs. #tamperTuesday #ontrackplant #OTPliveries

In 1996 Tarmac acquired the Central Track Renewals Company as part of the privatisation process and started operating under the "Centrac" name. Their livery was a basic yellow with white roof. #tamperTuesday #ontrackplant #OTPliveries

This year lots of older machines are getting replaced by brand new machines as some companies modernise their fleets. One casualty will be Loram's C2101 Rail Grinder which arrived in 2002. Here is DR79231-79237 (exc. 79234&235) passing through a gloomy Cardiff Central. #ontrackplant

Here's the first in an occasional series looking back at old on-track plant liveries, kicking off with the classic yellow with red BR double arrow logo and Civil Engineering Department signage. A couple of machines lingered about on the rail network until the mid-2000s! #ontrackplant #OTPliveries

Network Rail have put one of their Ballast Cleaning Trains up for sale. Closing dates for bids is 13 April. Most of the vehicles can be found at Fairwater Yard, with a few having recenlty moved to Tyne Yard. www.ontrackplant.com/news/network... #ontrackplant

Fifteen years ago the final Fastline machines at Bristol Marsh Junction OTPD (part of the larger St Philips Marsh site) were being cleared out with several going for scrap, some abroad and one for preservation in Swindon. February 2011 #ontrackplant #tamperTuesday

Another Stoneblower off the list, although not entirely happy with the obstruction. Here are two shots of DR80216 taken a few minutes apart in very changable weather! #stoneblower #ontrackplant

Network Rail Harsco Stoneblower DR80215 makes a spirited departure from Crewe. This machine is returning to Scotland (via a stop at Preston) after its yearly service at Harsco's works in Derby. 19 December 2025. #stoneblower #ontrackplant

Made a good effort with last year's Stoneblower photo goal - filled in five out of eight gaps - including the Scottish one which I didn't think I'd get. Will aim to get at least two more this year (not sure I'll manage the Worksop example ☹️) #ontrackplant #stoneblowers ontrackplant.com

Bristol was good fun over the weekend. Visited 100 times with work, so nice to see something other than a meeting room.

Here is a short round-up of on-track plant news during July 2025. #ontrackplant www.ontrackplant.com/news/on-trac...

At the start of August 2025, Alstom and Railway 200 hosted a long open weekend at Litchurch Lane Works celebrating 200 years of railways. A number of machines were on display and are listed here. Members can log their sightings using the page. #ontrackplant www.ontrackplant.com/reports/grea...

Some more crusty wagons were visible in a siding and only viewable from a train ride. Highlights include a cut-n-shut double length Freightliner twin wagon; some Conflats, and who knows what else. * Would've gladly paid for a Wagon Walk Experience to get closer to these! #TheGreatestGathering

Lurking in a corner at The Greatest Gathering were these interesting crusty old wagons. One was an "Internal User" shunting runner wagon; and the other a large flat wagon marked "LUL Material Only". #TheGreatestGathering

Often overlooked by enthusiasts, these items of plant on display at The Greatest Gathering were all built in Derby. The Rail Grinder was built at Loram's facility across the road; and the small metal trolleys were built by Donfabs & Consillia #ontrackplant #TheGreatestGathering ontrackplant.com

A variety of Readypower machines were seen near the Severn Tunnel at the start of June ready for the large blockade in the tunnel. #ontrackplant ontrackplant.com

A large gathering of APWebb machines were noted at Patchway at the start of June ready for a large engineering blockade in the Patchway/Filton area. #ontrackplant ontrackplant.com
