What is with the association between trains and death? Why, out of all vehicles, are trains the most common choice of afterlife transportation? (TVtropes has a whole page of examples).
What have trains got that, say, a bus doesn’t?
This has been on my mind because I recently got my hands on some model railroad supplies, and was undecided about whether to shell out for the expensive part (ie a locomotive) until it occurred to me that I could make it into an ancestor shrine, partly due to this trope.
