How about they put a big toll booth on nthat railroad and let the AMTRAK riders pay for it???
The state is missing a lot of revenue by keeping round trip fares at rock bottom prices. The ABQ to Santa Fe senior fare is $3 one-way; a round trip fare for a senior is $5 if purchased online ($7 and $8 otherwise).
Consider that if you go to Santa Fe and have a meal at just about any restaurant is will cost you $15-20 minimum, more with a drink. The ABQ/SF route is very popular with tourists so they could double or even triple the fare and it would still get lots of patronage. The Martinez administration needs to look very seriously at fare increases if it intends to keep the RR running.
