Construction

Guide-way construction is comprised of caisson pilings, casted pillars and pre-fabricated spans. 

LARTs interchanges:
  • PARK n' LARTs at existing road junctions with the M25 link car journeys with railway stations, airports, and business parks
  • Railway Stations are easily accommodated with LARTs using the elevated architecture over the existing platforms
  • Airport access to existing terminals or depots, achieved with small bore tunnels or elevated guide-ways
Guide-way construction utilises proven pre-fabrication techniques and temporary yards along the route are required. Box sections comprised of monocoque fero-concrete or steel, are transported at night and assembled on site during the day. 

The pillar construction permits minimal soil movement along the route for minimal disruption during construction. Height of the guideway essentially follows motorway grade within an few metres. Where the motorway is in cut, the pillars are placed into the embankment, and where the motorway is a bridge LARTs can be constructed at the same level.

Most bridges crossing the motorway can be negotiated by routing the tracks for LARTs 'under' the bridge or the earthen approaches. The small train dimensions make this feasible, and that permits small bore tunnels where necessary.

The minimal disruption of construction reduces costs significantly while the grade system does not interfere with existing road surfaces.

Components of the guide-way are transported during off-peak periods at night, while assembly takes place during the day away from the useable road.
