No, this is not a joke, I am being serious
Please don hang me

and let me get you a drink !
It seems kind of unrealistic and unsatisfying to have a track ending in nowhere, especially when the only reason is that the route builder had to stop building (just because he can not go on forever). In real life that track goes on and on for thousands of more miles.
I got this idea when I was driving a route where the quality of the scenery got lower and lower, but I kept driving, then suddenly the world ended . . . no where to go, only option was to reverse. So I thought
why not have a tunnel so I can pop up at the other end of the rail road. Just as many scale moddelers do when building a rail road, at the end of the track the train goes behind the scenes (is fiddle yard the correct word?) and circles back to the beginning of the rail road.
A better realistic option might be to have the track end at some kind of disaster. collapsed tunnel, flooded bridge, cattle on track, damaged track, rocks on track, train wreck, etcetera . . . . In that case it is very realistic and not unsatifying at all that one can not continue.
