dude.. this problem has been discussed many times.
Developers here cant make routes 24/7, theres other important things that has to be going on in peoples lifes. such as personal things, jobs, schoolwork, etc. In other words, these routes and trains for openbve may not even be released. As all I know, developers here can only develop trains/routes in there spare time. Not every minute of their lives.
If you have the time to make a train or a route where you can spend every second of OpenBVE, go right ahead and start building your own train/route.
