One element of cost escalation was given above: rail-rail grade separation. There is no non-artificial reason why the LRT can’t cross the rail line in the same way as a bus, or with the benefit of a signal interlocking. Either way, access to the diamond is controlled such that the chance of a train and an LRT both trying to occupy it at the same time is reduced to very close to zero. It’s only a form of safety paranoia that makes us unable to build an LRT system with a level crossing of a freight line.
