Below is the Tamper.
Ex Balfour Beatty 73214.
In this case fitted with 4 tools.
The whole unit is vibrated then plunged into the ballast bed either side of the sleeper. The tools are then squeezed to pack the ballast under the sleeper.
They can lift Vertically and slew Horizontally to achieve the required track geometry.
Some tampers use a hook instead of rollers.
The clearance to the trolley is very small any excess ballast will damage the feeler rods.
He cannot see at all forward and very little to the rear.
At night this area is floodlit as are all main areas around the tamper.
The additional weight is to counteract the tendency to climb the rail.
This is only approx 40mm lift.
I have seen over 100mm on some sites.
Front and rear trolleys, Clamps and banks all stowed and secured.
The group have purchased another Tamper. 73250 from the Kent and East Sussex Railway.
The Tamper arrived on Monday 17th June.
This tamper is a few years younger, being built in 1977 and looks very similar however beneath the skin the Tamper is more suited to computer control, taking pressure off the operators trying to achieve the required track design position.
