Everyone has probably heard about this already, but if not here is a link to news article about the TRAX collusion that happened Tuesday night.

UTA is very lucky that no one was killed. A 40 mph impact with a stationary car could very easily be fatal. Some serious operarional canges are in order.
For example, bypassing a red signal will hopefully now come with a speed limit. On Frontrunner, this speed limit is going slow enough to stop within half a sight-distance. Something similar should be done on TRAX. This will significantly increase the amount of time it takes trains to enter or exit the yards, where bypassing red signals is the standard proceedure.
Also, UTA couples and uncouples its LRT cars much more than is recomended by Siemens, the manufacturer. This constant rebuilding of 2 and 4 car consists throught the day wears out couplers, which UTA is reluctant to replace as each coupler costs around $90k to replace, when labor is added in. In order to follow the manufacturer's recomendations (reorganize the consist only 5 times a week at most) UTA is going to have to either 1) run 3 car consists all day, or 2) have entirely separate consists of 2 and 4 car trains entering and exiting service throughout the day. UTA does not have enough cars to do that. If they continue to wear down the couplers with their current operational practices, they will continue to have mishaps. I'm told this isn't the first time cars have come uncoupled at that location; once, it involved passengers.
So even though there were no fatalities. this is still a huge deal for UTA.
