doctorwayne's 2021 Do Something Challenge - Part 1

What are the things that look like finish nails sticking down from the floors?

Surprisingly, they are finishing nails, but they're meant to represent vapour regulators (often referred to as "steam traps").  The Branchline (now Atlas) passenger cars have ones in plastic that are much better-detailed , but all I'm attempting to do is make it look like there's important stuff under these cars.  Once they're painted, they fit in pretty well, without drawing too much attention.
