Amec Rail's Wet Spot machine is based on the main frame and running gear of a Plesser PBI-84 stoneblower. With the addition of a vacuum unit, spoil hopper, tamping bank and a purpose-designed ballast wagon it has been turned into a complete solution for dealing with wet spots on the track.
The wet spots are excavated with the vacuum unit, backfilled from the ballast hopper wagon and then tamped using the integrated tamping bank. During treatment, integral safety barriers extend from the machine around the working area. This creates a zone where operators can work safely, protected from the passing traffic.
Excavated spoil and slurry is held in a hopper and discharged to the cess area from either side of the machine. The entire operation can be carried out in a single line possession, Amec says.
