No? was there something i said that was mocking you? genuine question.
No worries. It just seemed to me that the reply about switching taking a long time seemed a bit snide (as in implying childlike ignorance). I was probably being too sensitive! Don't worry, I get accused of this all the time by my wife regarding things I'm an expert on that I'm incredulous that she doesn't understand. We're still married so far.
you had mentioned safety switching so i was thinking you meant for them to have switches swap the trains onto the lines.
Ah! That's a total mistake by me. I meant *signaling*.
I think the downside to the crazy additional inline station idea is the following, say at closing:
Step 1: Train 1 approaches the MK stations A & B. Both are empty. It bypasses station A and goes straight through to stop at station B.
Step 2: Train 2 approaches MK stations A & B. It stops at station A.
Step 3: Train 1 completes boarding and departs for the TTC.
Step 4. Train 2 completes boarding and departs for the TTC. Note that it bypasses station B.
The safety questions are:
1. How close can MK Station A and MK Station B be?
2. How soon after Train 1 stops at Station B can Train 2 pull into Station A? This is mostly a question of how closely it can be to Train 1 while in transit from TTC to MK. The smaller the signaling zones on the track between the TTC and the MK, the closer they can be and the sooner it can pull in.
Those answers combined with the boarding time of the trains gives us the increase in throughput that one could get from the crazy double-station idea.
Zoned and signaled properly, I could imagine Train 2 pulling into Station A just 10 seconds after Train 1 pulled into Station B. If this is possible then it would be (mostly) comparable to having two parallel stations with a beam switch that operated in 10 seconds. And if it takes 60 seconds for a train to fully board, this is only 20% less efficient than having a double-length train.
