VL they are two images layered

I have a crop not FF and lowest my kit lens does is F3.5
So I took the station at F11, 2 secs 18mm, ISO100
Then took the trains at ISO10000 18mm, 1/250
I then used photoshop to smooth the bloody noise out.
Then used photoshop to layer the train over the station
Complex and probably one of the more harder things Ive had to do. I dont know whether a fixed f1.4 35mm lens would have helped with the light, or, just plain and simple reached the limitations of my crop body.
I'll change the title. Thanks.
