I will check out his stuff again. Another option is to use the central artery for another Red Line tunnel, etc. Of course you lose some of the benefits with any of these cost cutting measures.

The São Paulo Railway Company runs freight trains that switch between adhesion and rack railway. I watched a video of the changeover and the train doesn’t even need to stop even though it has to travel slowly for that stretch. One of the companies involved says that, “One locomotive can pull up...

I'm not an engineer so please bear with me. How long do you think it would take to switch modes? Does the rack and pinion system require lower speeds than what you would have in a tunnel anyway? I know the equipment would be an expensive ongoing cost. The question is whether it is higher than...

Could they use a rack railway to increase the grade of the portals? This would shorten the tunnels and perhaps allow consolidation of portals. The decreased tunneling costs might make up for the need for new equipment. The grade wouldn’t be as steep as a mountain railway. It would be steeper...
