I prefer to save the gems first, i am level 121 now, and i start buying wagons for bonus like 250% since level 90. The wagons worth great, with a dissel loco. for a full train at 10 wagons, i could earn 10000 units of materials at a 24 hours ride. So don't worry about the maglev era stuff, you will have enough time to get all the materials you need for extensions while you are upgrading.
