Well, mate... I can only say there's a seeming lack of patience on your part, where track laying comes into it. I thought it was a bit hard at first, but after some bouts of continuous trying, I got the hang of it, and managed to lay some interesting lengths of track for my own use, albeit on level ground, mainly, I confess. I can lay gradients, and remove ground to one side of the gradient, so it looks like its deeper. What I haven't yet attempted yet, since buying Rail Simulator, and advancing to RailWorks, Then RailWorks 2, seems to be the actual DEM work, on ground that is shaped like real terrain is. But, I wish the creators of RailWorks could provide a tool that would make it far easier to shape ground and raise it for a wider area from either side of the track, then it would be easier to shape your own routes a bit more, like I managed to do with TRS2004, onwards, before Rail Simulator arrived on the scene.
I love working with RailWorks, but it gets a real pain, waiting longer and longer, the more assets you add to RailWorks, for it to actually load to playing stage. My computer is a moderately fast one, and I have at my disposal, three hard drives of 250 GB, including two external ones. The internal one is partitioned so I have two areas of storage, while I keep most of the downloaded files on the two external drives. I just wish I had a faster machine, and the ability to shape ground better, as it gets hard to terraform bona-fide routes that aren't actually real-world areas. But I really can say it wasn't all that difficult to learn track laying. It does require a bit of practice. My advice is: Once you get the hang of it, it stays with you, definitely. Don't give up - keep trying, and you'll appreciate it greatly. I'm still learning, and enjoying it.

(Even if it's only for your own pleasure, and only for fun, but you might persevere, and go on to make stuff for others to enjoy.)
