The extensive and fragile signaling system is just too exposed and the track must be segregated, either by tunnel, viaduct or Berlin wall style fencing.<BR/><BR/>The Southern region electric railway in the UK has many level crossings, despite the fact that the system uses the "3rd" rail pick up. The French have successfully used the APS electric system, which electrical pick up is done on a special "3rd" rail, flush on the street, without danger to vehicles or pedestrians.<BR/><BR/>SkyTrain, being a 'drverless' system, needs a segregated rights-of-ways.Light Rail Guyhttps://www.blogger.com/profile/08422776386583809414noreply@blogger.comtag:blogger.com,1999:blog-3299108886803608881.post-22696481155164904392008-12-12T11:48:00.000-08:002008-12-12T11:48:00.000-08:00yes, it would have to be like 29th Ave which would...yes, it would have to be like 29th Ave which would make the areas were at-grade could work very, very limited...

Now if only we could get Falcon out of the way...<BR/><BR/>and p.s. there's no way the skytrain could simply descend to an at-grade track is there? (I assume the track electrifying would be too risky on ground level, unless it was barricaded up ala 29th ave station)Robert W.
