Hey everyone here is my latest project:
Hope you like it 
Firstly, I like the render…and it gives you an interesting perspective.
Now, this next part is because I am a train fan. My issue is with the red light. You have a single track. A track like that should not have a light on it, or…there should be a reason it’s red, i.e…a train is coming.
I’m not sure if you are planning on adding a locomotive in here, but…you could really do something interesting with what you have. 
The rails look wrong. They look as though the top surface is flat but it ought to be slightly rounded. They also look too wide unless this is a narrow-gauge railway. The signal is the wrong way up. Railway signals always have red at the bottom for safety reasons (so the red aspect can’t be obscured by snow etc). I am not sure about overhead cables but if that is supposed to be the traction current supply I am sure that there ought to be more wires. Certainly what I have seen on UK railways have more complex arrangements than this even if only to allow trains still to run if an overhead cable develops a fault.
@tc2466 There is nothing wrong with having a signal on a single track line. It could be approaching a junction where the single track branch joins the mainline.
I had absolutely no idea that there are so much train fans in the blender community. 
I have not spend time researching the internet on how a railway actually looks like ,where signal lights are placed, where the red light is … maybe this was a mistake if I think of it now but I had an idea in my head and just went with it and I know it is not 100 % realistic but that was not the aim of this image.
But thanks for your feedback guys
