Another restart of this station, pretty happy with the model this time though, texturing what I have done so far as with an earlier attempt I found I couldn't select faces once enclosed. So this time I will complete the texturing of the model so far before mirroring the other platform and building up to street level from there.

Still a lot to do, I am finding I can knock a model together in no time at all but texturing is a completely different matter, this part is very time consuming but I am learning as i go, I think I will need to complete this model 100% before moving on so following stations should run more smoothly when i understand better what I need to do.
