One of the best ways to avoid the tedium of building tracks, IMO, is to not try and do them all in one go. Most people build the whole model and then start on the tracks, meaning they have a lot of dull work ahead with nothing else to break it up. It's far easier if you clean up the parts and build the track in stages while working on the rest of the model, like when there's something drying that you need to wait for, or just as a change from what you were doing.
