I made the ceiling lighing for the station. Based upon 1930's lighting so it can be accurate for the times. They have been made to look like massive, almost chandaleir-esque lights. Using transparant materials for the light shade i then could put a light emitting object inside it which casts the shadow of the lens shape over the ground creating a nice effect.
I doubled up the station and track to add alot more background and of course it wouldn't be a single line railway in a city anyway. I positioned the lights so that the shadows how the most effect. The next step i need to take is drawing up benches and pillars for the middle platform. and benches for the other outside platforms, and also finish the clock off. The clock is taken straight from the german expressionist film "metropolis".
