Seriously, Amtrak solved this problem 20 years ago:
The battery operated portable wheelchair lifts are around $5000 per copy. Crank-o-matics using cables and a boat winch are less than that. Perhaps another $2000 to have a shed to lock it up and protect it from the weather if there's not suitable indoor storage at the station.
I don't think you're building a mini-high for that little, but if you can, great.
Sometimes I think bi-level equipment advocates throw up meaningless obstacles just to throw up obstacles... this just isn't a hill worth dying on, Ron.
I'll admit that the mini-high is the best option for commuter service because they're more likely to see use, but in a low volume Amtrak flyover country stop, it's a waste of time and resources.
Fortunately, those states (TX and OK) operate with balanced budgets and find a way to make things work within the means they have.
