The downside to LIMs is that they have ann unexpected derailment/failure mode (1), as manifested by the 2023 SRT derailment.
Briefly, the magnetic repulsion/attraction forces of an accelerating train caused a section of the reaction rail to catch on the train, which catapulted a train car.
I’ll also mention used to live near the SRT. They were still great and quirky around the 10 year mark. However, the Mark Is didn’t age well. They just got louder and louder.
They also became more and more susceptible to severe weather, to the point they were run in manual mode (versus ATO) with every snow storm.
