But much of the length is, in fact, single-track, making scheduling hard and meaning if a train is late or breaks down it disrupts the whole system.
And it's honestly pretty silly to see a train with the form factor of light rail but diesel-powered.
Voters did approve a proper light rail system in 2020 but it's gonna take a while to build and has already been scaled back twice, sigh...
