The UK is a world leader in light rail passenger train systems and what they frequently call "community rail". Being the smart folks they are, they have found a solution to this costly mess with the LR55 tram track system. The system allows for quick installation and uses the existing road structure to support the load. This is revolutionary!

"To avoid or reduce these problems NET proposes to use the revolutionary LR55 rail system. This is laid in the road structure itself so that there is little or no disturbance to underground services. Instead a slot is cut in the road and the track laid in. The track exploits the strength of existing highway pavements by transmitting the static and dynamic loads from the upper surface, rather than the foot of the rail as in conventional track. This results in the load on the railhead being distributed onto the sub-base of the highway, being of a sufficiently low value not to require a separate foundation. Up to 100m can be laid in a night"
