Hi,
Rail Clamps - maybe the items clamped onto the rails between ties to keep rails from creeping?
Rail anchors (anti-creepers)
Car wheel chock, bolted to RR ties, iron, 40 cm overall - This works out to about 15.75" - I wonder if they are the rail skates.

I do not think Rail anchors were developed until the mid-1950s.
FWIW
