TL;DR: Someone who actually knows trains points out that the designers eliminated all the benefits of rail while designing something that requires the entire existing rail network to be changed to support it (which will never happen). I think the biggest nail in the coffin is that they are targeting short haul lines, which are often the least maintained and require human supervision to operate on for safety and logistical reasons. For example, short haul lines use manual switches - so every time two tracks split or come together you have to have a human present.
