You have to train bus drivers just like you have to train train drivers. In either case they are in the same or similar unions so will be paid similarly.

I know that any company requires training, I never claimed otherwise. However, I assure you that in several countries it is far easier to find a person capable of being trained for a BRT than a LRT, including mine where there's basically 0 train infrastructure. This higher skillet requirement, and therefore higher salary, is mentioned in the reference I posted.

AND that’s the whole point, you can couple train cars together. You can’t do that with buses.

I feel like you are confusing HRTs and LRTs. I see HRTs as better alternatives to BRTs, but BRTs as better than LRTs. Looking at some number online, Dalla's LRT has a very comparable capacity than that of Bogotá's BRT, as it is smaller per vehicle; I'm not saying this implies that BRT is better, as Bogotá's has in its fleet the biggest BRT in the world, just saying they are definitely comparable. Granted, this is not a systematic comparison, and you'll likely think I cherry picked, but I just chose Bogotá as that's where I live, and Dallas by looking at a guide to LRTs

This comes down to high initial cost just because that’s how it works and then lower operating cost.

Initial costs is usually paid in the form of loans, so it is an operating costs as well. This was mentioned in the reference.

I think it's fair if you consider I'm discussing in bad faith, this is not my field of expertise and I'm pretty ignorant in the topic, despite some efforts. However, I really think that my bad-faith is not out of sheer lazyness.
