Today's job was a stretch of track which basically covered the through line of the former Laverton loop, starting a few dozen yards south of it.
This involves getting out the trolleys and support bars behind it, with a pair of steel wires which run from the farthest trolley, through the machine and all the way to the forward cab. This arrangement allows the machine to measure where it is going and what it should do.
It's an older arrangement, no longer required by the newer Mk5, but it worked fine, as we could see afterwards.
Here is the pair of trolleys, bars and wires fully rolled out.
Progress was pleasingly rapid, once all was set up.
The slightly irregular path of the rails can be made out; this is what we came to fix. The location is the through road of the former loop at Laverton.
In particular the area north of Laverton bridge shows a larger than normal dip, coming off the raised level of the bridge and its thicker deck. Manual jacking here to raise the track to a level that the tamper can handle easily proved fruitless, and a jacker / packer has been hired in for next week to do this.
The tamper then arrived at Laverton bridge, here doing the last few yards, being observed by Neil, who had come to move the machine to a second site at Toddington.
Shortly afterwards the tamper passed over the pulling point, and did a few more yards up to the top of the bridge.
This was the end of the first job today.
Here is the tamper stopped just before the pulling point, with Laverton Bridge in the foreground.
The class 73 is poised in the background, ready to haul the tamper back to Toddington for the second session today.
|The tamper has paused on Laverton bridge, at the end of its run along the loop.|
On the way back to Toddington, we passed this kit of parts for an engine that could be very useful on our line, being modern and not too hungry for coal.
Anyone see what it is yet?
The second session also went very well, and we did more than expected.The tamper worked its way all the way up to the signal that can just be glimpsed in the distance, just short of Stanway viaduct. This will be the starting point for Monday.
A quick glimpse into the shed at Toddington showed that work on the authentic canopy for Broadway continues.
