it is looking prety good for an early WIP, but i do have some recomendations/thoughts that i thought i would throw in there.
1. i would recomend changing the bridge to the tallest one avalable since a bridge with that long of a span needs all the extra support when a train crosses it.
2. I would also recomend that you smooth out the tops of your mountains to something a bit bigger and not as pointy. i am shure you will address this because this is only in it's early stage and you are getting the feel of route bulding still.
3. Now looking at the yard in the town i would say to add a Wye at the end so you have some place to turn your steamers around, this would be very prototipical of the general area and the time period being modled. If you are having issues with corrners not being tight enough on your track from 3DTrains, on the right flyout you will see a slection that says mainline, click on the slector beside it and select yard, that rule will give the tightest turn radius which i find perfict for this era.
great job for your first route!
