[https://www.chaski.org/homemachinist/viewtopic.php?t=110289 John Atkinson posted the following on <i>Chaski.org</i>]:
 
: As you may already know, the subject of signal foundations falls into one of the elusive subject matters seldom if ever discussed within the miniature railroading hobby.
 
: My research and observations along the way have formed the opinion that manufacturers of full-size signaling equipment also leave the requirements for the foundation to the engineering department of the railroad [itself] for determination.
 
: I’m hazarding a guess the reason for this is because each installation calls for its own answer.
 
: Clay in North Carolina verses sand in Northern Michigan to give an example.
 
: Just for fun, I’ve taken the drawing of a [[Roll Models Industrial Railworks|RMI]] grade crossing signal and matched it to an actual foundation drawing for a full-size instrument case to provide a form of visual reference. It looks like the foundation required for the signal could be close to three feet in depth.
 
: Does the foundation for the [[Roll Models Industrial Railworks|RMI]] signal need to be as robust as it appears in the screen shot?  Probably not, but again… it would depend on where the signal was intended to be installed.
 
: Last year I played around with making a foundation for installing a signal measuring 5 foot 8-1/2 inch tall.


: Because I had previous reference material on how the signal had been mounted in the past,  I made a guess and cast a couple of new foundations approximately 15 inches tall.  The signal has been installed, has endured wind from passing storms etc, and is still standing.
The [[Annetta Valley & Western Railroad]] uses wood for their [[Grade crossing|grade crossings]], as described by club member Tom Stamey:


: For what it’s worth, the design feature of the below grade voids on all four sides of the foundation provides an exceptional gripping of the earth and should be implemented into your own ideas if you can.
: For repair of crossings we need 1X2 inch lumber in 8 foot lengths. It takes 5 pieces to protect the two rails if they do not get heavy loads pulling over them. If trucks and cars go over them they need to be protected by two boards each outside the two rails plus the 3 pieces inside the rail. Extra long ties are needed about every foot so the additional boards on the outside can be screwed down with wood screws. All protection of the crossing must be screwed down.
 
: Three pictures attached for reference.

The Lakes Park Railroad Museum railroad uses a novel method for constructing grade crossings.

AVWRR Example

The Annetta Valley & Western Railroad uses wood for their grade crossings, as described by club member Tom Stamey:

For repair of crossings we need 1X2 inch lumber in 8 foot lengths. It takes 5 pieces to protect the two rails if they do not get heavy loads pulling over them. If trucks and cars go over them they need to be protected by two boards each outside the two rails plus the 3 pieces inside the rail. Extra long ties are needed about every foot so the additional boards on the outside can be screwed down with wood screws. All protection of the crossing must be screwed down.
