Harsco RGH20C S&C rail grinder
|During the summer of 2003 a new
type of rail grinder was tested by Serco Railtest on behalf of Network Rail.
This was the RGH20C switch and crossing grinder built by Harsco in the USA.
The first machine was delivered to the Mid Hants Railway where
driver/operator training was undertaken. Whilst the grinder was operating on
the Mid-Hants the railway had most of its main line re-profiled
Judging by the state of some track on preserved railways I think they got
themselves a good deal.
I remember visiting the railway one Sunday evening in the summer after the public service had ceased. The visit was for our traction inspector to approve the drivers and train crew for operation under Serco's safety case on the main line. What a job but some body had to do it!
There were several loco-hauled transit moves undertaken by Serco between Hampshire and Derby prior to the machines being allowed to run self-propelled.
Altogether five RGH20C grinders were introduced into the UK.
Serco Railtest carried out all the statutory acceptance tests on the first machine Nos: DR79261 and DR79271 including runs to Carlisle via the S&C. We then assisted Harsco and Network Rail in operating the machines during the commissioning and equipment acceptance phase up until the end of March 2004.
Here are a few pictures of the machines in action and a couple of more recent pics.

Soar on the Midland main line on its way from the Mid-Hants Railway to the RTC
|Machine No: 1 waits to depart Hither Green depot for another shift on 17th January 2004. On 3rd rail systems, following an incident when the protective curtains shorted out on the live rail, they were usually not fitted until the unit was on site.|
|Later it is pictured at London's Blackfriars station where it stands in the platform prior to commencing work|
|On 20th January 2004 machine No:3 is pictured at Darlington where it was stabled during work in the area.|
|By 28th January 2004 machine No:1 was further a field and is pictured in the snow at Hurst Green station just south of Oxted.|
|In the snow just south of Hurst Green on the line to East Grinstead|
|On 16th February 2004 the work was just outside Victoria station where the machine is pictured at some unearthly hour.|

|We catch up with machine No:2 during its daily servicing at Chester on 17th August 2006.|
|No:2 waiting for the night shift. Note that the protective curtains are fitted.|
Serco also operated the Loram C2102 grinder which also had undergone acceptance testing during 2003/4 although the author was not involved. Here are a couple of shots on the main line and at the GC. Photos courtesy Andy Wheatley
