Sorry if this has been discussed before; I am new
to the group.
Is there any standard anyone uses for thickness of
roadbed? The original laying of track, I assume, was
right on the ground in a big hurry to complete the
line. I saw one picture of track layout with 4 1/2'
ties. The proportions made it look just like a
standard gauge track. 1/3 of the tie between the
rails and 1/3 on each side. Later pictures show much
longer ties. I guess in some cases, they bought
standard gauge ties but I think mostly the ties were
cut locally and probably never treated.
Later, as maintenance required it they laid ballast
and lifted the track out of and onto the top of the
ballast. Many pictures do look like the depth of
gravel from the bottom of the tie to the ground was
zero. Many pictures do not have dates and I think the
practice changed over time; I suppose that means you
can do whatever.
