The studio has been in mega production this week with a look at how our track is maintained with a little help from the Trackwork tamper. The PWT as shown moving ahead of the tamper filling sleeper bays that are a little short of white gold. The machine makes a pass over a section to be tamped to download the geometry of the track and then is able to pack and line as it progresses. The pauses are to let manual intevention deal with sleepers that are slightly out of regular spacing. Wonderful stuff and a great help to our enterprise.
