Your whole argument rests on the following:

"The CBTC system permits a 2 second delay to/from each train."

Source?

If this figure is not accurate (ie if the TA's CBTC system's communications delay is only 1 second, then your whole argument falls apart.

Also, from a standing start, 4 seconds does not translate into 240 feet. It only does so "at speed." CBTC allowes much shorter interval spaces in the context of starting and stopping trains at stations, which is where a lot of the savings occurs.
