Crash Avoidance System Plays Havoc With SEPTA LRVs
The Philadelphia Inquirer reports that crash-avoidance technology installed on SEPTA light rail lines is causing "chronic rush hour delays" despite spending $25 million and working for nearly a decade to de-bug the system. The technology is used to prevent rear-end collisions between light rail vehicles in a 2 1/2-mile tunnel running from Center City to the west side. But, it causes trains to run too slowly and results in backups.
