The contract was to install third line track drainage at Northumberland Park West Anglia mainline rail station.
The project team used an excavator slew and boom restrictor to comply with Network Rail ALO (any line open) working procedures.
The project required excavation and removal of spoil to a designated storage area. Drainage was installed to the approved design adjacent to the running rail (up Cambridge line).
As required, work was kept more than 3m from the nearest running line and did not affect the track support zone.
