HOME PAGE - Light rail around London

The LONDON AIR RAIL TRANSIT system is a proposal using tried and tested engineering and technology. 

The purpose is to link all modes of transport around London, to enable sustainable growth for commerce and people by providing greater convenience for travel by road, rail and air. 

LARTs incorporates automated light rail technology to deliver capacity, connectivity and contingency for door-to-door journeys for commerce, tourism, air-cargo, railways, buses, and airlines. 

The concept uses existing transportation corridors, and takes advantage of the M25 corridor which crosses all of London's mainline railways and is adjacent to the major airports.

The civil engineering utilises proven methods, to improve existing infrastructure with minimal impact and disruption to people and environment.

The business case delivers an optimal rate-of-return with sustainability that is fit for purpose as a Private Public Partnership (PPP) and a Public Limited Company (PLC).

The aim of LARTs is to integrate this segregated light rail system with the mainline railways, the major airports, and arterial roads, to add capacity and add connectivity to all modes of traffic.

Existing bus networks can be combined with LARTs plus parking to create multi-modal park-and-ride sites called PARK n' LARTs.

The fare structure is based on mass transit travel tariffs, and the benefits brought to other modes of travel plus regional development, create positive economic benefit and therefore minimal demand on the public purse.

Surface access for the airports at Heathrow, Gatwick, Luton and Stansted is combined with a degree of inter-linking the airports to provide the one viable option that reduces road traffic around airports by a greater degree than any other proposal.

Air-cargo and airport users can, in many cases, be moved between mainline railways, arterial roads and airports more quickly and reliably, 24 hours a day. LARTs enables off-airport services, such as parking or air-cargo, while using the full capability of light rail to be constructed close-in to airport terminals and railway stations either above grade or using small bore tunnels.

LARTs integrates with radiating railway lines from London that cut across the M25. This delivers more rail connectivity, adds capacity and frees up capacity, whilst adding contingency routes and resilience to London's railway network.


Using only brown land and requiring no demolition of existing infrastructure are both social and environmental benefits. 

Enhancing Motorway capacity, is achieved by putting more people along the same corridors. PARK n' LARTs permits many car journeys to be curtailed by driving to the Motorway but using LARTs for the Motorway portion of the journey that links people and cargo, with airports, railway stations, business parks, and various town centres.

Regional railways links to airports and other railways can be quicker and more convenient using LARTs, rather than routing passengers through central London. This applies to journeys by both new and existing railways while LARTs adds overall capacity with its orbital links around London.

Capacity is added to the Motorway corridors of the M1, M4, M3, M23 and M25 by transporting the equivalent number of people as two new lanes of traffic. As London's footprint grows toward the M25 corridor, LARTs will provide sustainable options for the present and the future.



The LARTs guide-way, is primarily elevated alongside the motorways, thereby requiring minimal soil movement. Height is generally only 2 metres but can exceed 5 metres on single pillars in a few necessary circumstances. 

The dimensions of the guide-way and trains is well suited to going under most overpasses on the Mototways
This will require small bore tunnelling in some cases and these techniques can  be achieved with minimal disruption.

Minimal disruption and environmental impact is achieved with all phases of LARTs from construction to operation. 

LARTs uses train technology that operates 24 hours a day in any weather (rain, snow, ice, wind) to transport passengers with consistent reliability that will provide resilience to travel by road rail and air.
                                           
"With benefits for all", Larts delivers economics that are fit for a "free enterprise" strategy that begins with integration and capacity for the immediate future and the next century.
