Lay train?

Question

what does "lay train" mean?

Answer 1

Never heard that one.

Mis-spelling or phonetics problem, maybe?  I can't even think of a sound alike for "lay train," except for a song, "Take the "A" Train."

There is the "L" or "El" referring to an elevated train.

That's all I can come up with.

Answer 2

I think it it might be short for a tracklaying train. This is a train which carries the sleepers, rails and all the equipment and materials for laying the track, plus accommodation for the workers. They go out at night or on Sundays when trains are few and far between or nonexistent, to carry out the vital work of repairing or renewing the rail tracks.

Answer 3
