My commute into Edinburgh is about 35 mins each way by train and it's £9.60 for a return (reduced for a bit because of a subsidy by the Scottish Government) normal price is about £15.00.
I'm in the US. We wanted a commuter train in my city - instead we got a very expensive toll lane built by a Spanish company. The tolls are so expensive by the mile that only the wealthy or those with a business that can write them off as an expense use the lane. If the company doesn't make enough, our taxes have to pay for the shortfall.
I actually like my commute into Edinburgh - it's very scenic, you go over the Forth Bridge and I always get a seat. There was a while when the trains were less reliable but since the Scottish government took over direct management of the rail company things seem a lot better.
