As has been stated, there are IRT routes in development. However, these routes would get done faster if the community contributes instead of complaining. I have been working on updating my highbridge line, which is an IRT route, so that you would have IRT eye candy to hold you over until the real routes are completed. However, that project just as the real IRT projects have been stalled because of repeated requests for straight photos of IRT walls and no one has attempted to help out by getting some. We as developers cannot provide you with eye candy without the proper textures. I know for a fact none of you want to see and IRT route with IND walls. Then it's not IRT now is it? The same goes for the BMT routes. The walls are like IRT. Until we can get the proper textures, you will just have to wait.
