The hosting costs of websites on this system have historically been covered by advertising. However changes in the way people use the internet, including ad-blocking mean that the revenues no longer cover the expenses. For this reason we will be closing this website within the next two months unless we can find a different model. If any users of the site would be interested in the possibility of taking this incredible archive or pictures and comments over including paying for hosting, please get in touch.

Photographed southbound approaching Grantham station while proceeding to its next job on 21 March 2011.
When in operation, this machine measures the line and level of the track, and either computing, or working to a design, lifts any slacks or dips out of the track, where necessary slewing the track from left to right if there are any errors in the line. The tamping banks have tines that vibrate at a certain frequency which when driven into the track settles the ballast under the sleepers. The tines also squeeze the ballast under the sleepers.
The far end of the unit has a Dynamic Track Stabiliser (DTS) that again vibrates the whole track unit to bed it in, and simulates high levels of traffic going over the line, meaning that the track can be put back into service with a higher line speed, also minimising the number of additional tamps needed after the work.

this one doesn't have a DTS system on it only a double bank tamping system, worked with it the other night at Brooksman park.
