...I still like the idea of having several, maybe 3, taxi's cued up at the station rear in addition to the taxi in the front.  I could envision how that would work: When the front taxi moves out, the first cue taxi advances to the front.  The remaining two cue taxi's advance in position, one taxi at a time.  When  the taxi returns from the loop, it stops at the back of the rear cue.  Delays would still be used, however all the taxi moves must be completed before the loop taxi returns.  Also, this would only work if the cue taxi's were manually placed in their starting position.  Seems like this scene should work if cue size is varied to 1, 2, or 3 cue taxi's on the layout.

Right.  It seems you could just use traditional "red-green" block signaling with any occupied block disabling power to the next block.  The key would be to have the taxi stop ON the sensor so that you don't need to mess with latches - whether this latching is done with relays or digital logic chips.

I'm not familiar with Super Street taxis but if going slow enough, I'd think they might be able to stop ON a sensor even with coasting momentum.  To insure this, perhaps run the voltage to the queue blocks a couple of Volts lower using 50 cents of 3 Amp diodes (using diode dropping).  If starting Voltage is an issue, simply use a $1-2 delay OFF relay module to temporarily boost the voltage to a block (for 1 second or whatever) to get the taxi started.
