How much is it to ride the transfer bus?

$1.25 per bus ride, if you get on one bus and need to get on another at the station ask the first bus driver for a transfer. The transfer will be used on the second bus instead of $1.25

Yes. And you can transfer from the Middletown MTS to the BCRTA R-1 bus and then go to Hamilton Ohio and get a transfer from their and then go to... Tri-county Mall, or Miami University in Oxford Ohio. All with the first transfer.
