get some practice with the flex track tool usage. The flex tool will also shape the roads.
The baseboard editing and creation requires a little more study also. By highlighting the baseboard, right-clicking and using insert points I was able to create the center opening. Using absolute coordinates is the method that I use to create specifically shaped baseboards(tables, decks)
If you run a scale engine on the outer loop, you need an arrival/departure track to drop off/pickup trains from the mainline. The inner loop trains can work the locals and makeup a train for delivery to elsewhere out on the mainline.
Investigate the footprints of accessories and create the building close the actual size. Practice with the measure tool to set accurate placement.
The tracks to a specific engine house require a specific center rail to center rail spacing. The track next to the engine house is probably too close.
learn to use the simulator in Extensions and run trains to decide if the layout does what you want it to do.
All considered, not a bad effort at learning to use the software.
