Briansilvermustang, That photograph evidences that train tracks really did occur very close to the fronts of buildings, like in a business district or in front of a row of stores. We see such arrangements on layouts, from time to time, but know that is often due to space constraints, so to see an example of such proximity in a real-life photo is interesting, to me, at least.
Here's another example somebody shared that I found equally instructive and surprising...
Interesting.
