Unless you plan to count the same rider that rides the bus, then transfer to the rail as 2 riders then you might be able to say that, but fact of the matter is, if a person rides the bus to get to the rail it's still one person since that person only pays once so it's still 1 rider.
Tax basis still won't be able to afford operating costs cause with a higher tax base, costs of core services also raise, water, sewer, road maintenance, refuse service, parks, etc. not to mention increased bus service to get feeder buses to rail stations.  All those services will rise so it will basically void any increases to  whatever extra money will go to O&M for rail.
And you do know that whatever the minimum wage is, prices for goods will also rise.  Added costs to any merchant will always be passed on to the consumer.
