And no he didn't discuss a lack of a stop at Union Station, at least that I'm aware of. Perhaps someone asked privately. But frankly I'm not sure that it really occured to any of us to ask, since putting in such a stop would require a 3 block (6 round trip) detour from its route.
It appears to me that Amtrak's route probably crosses TECO's about half a mile to the northeast of Tampa Union Station, though. Building a vaguely Secaucus like station there might be possible.
Since the crossing of those two lines is a diamond, any stop by Amtrak would esentially shut down the TECO line for the duration of the stop. And considering how unpredictable Amtrak's arrivals are, that would create a problem for TECO.
And stop far enough away would mean that people would have to walk at least two blocks, maybe more. I'm not real sure just how far away the block signal is that would shut down TECO.
Besides the amount of people arriving on Amtrak and transferring to TECO isn't very high. Most people on Amtrak have luggage and just take a cab or have someone picking them up. Perhaps if, and that's a big IF, Tampa gets its act together and installs LRT or additional street car lines, then maybe trying to figure out a way to connect the two might become practical. But for the moment, I'd bet that the OTOL gang probably represented half the transfers from Amtrak to TECO last year.
And I'm not trying to take anything away from TECO. They run a very nice operation, one that is growing in terms of ridership and it does provide a nice way to move around if you're close enough to it. They run their operation on a small budget, with some help from a charity, and all the employees that we encountered were a class act. But the Amtrak-TECO transfers just aren't there and I doubt that there would be enough people making such a transfer to consider trying to build an extra stop. Besides, I can't imagine Amtrak agreeing to make such a stop.
