Please read bottom quote and my response.
I wanted to say how much this was true. Each train is different, inside and out. Over the last 20 years, and almost even from the beginning, each train has developed its own personality. If one were to get technical, it could be blamed on the parts, but regardless, each has it's own attitude.
I've not ridden them, but have seen quite a lot about them, and heard from pilots as well as friends as passengers.
Red used to (and still might be) the one to either overspeed, or be the fastest train on the beam.
Silver in many pictures appears to be the lowest sitting train on the beam, often being just roughly a cenemeter lower I think.
Gold has been known to have quite a few technological issues.
I think Lime(?) Has been known to be one of the slower trains? Or has a hard time stopping...
There's even one I think that can often have a door issue, moreso than other trains.
@peachykeen can tell that what one train may reject, another may willingly take no problem! It's wise that they test the technology on a few trains to see if it WORKS, thus showing that the stuff was wired properly, and does work even before spending money on a new train. Peachy can tell (and maybe
@MonorailRed too) can tell you that each CAB is different in how it reacts with the components.
