The final step was to install rail, guard rail (optional) and a wooden edge rail (must
have).  Because of slight variations in height, some 2x4s had to be belt sanded to
provide a flat plane for the rail.  With careful 2x4 selection and placement, this is a
minor problem.  Both the guard rail and the edge rail are safety items.  The guard rail
captures a wheel if it derails and prevents the engine or car from traveling sideways
over the edge. The guard rail needs to be spiked about every fourth tie.  The edge rail
is a backup system.  If the wheel in not trapped as designed, the wooden edge rail
will usually stop a derailed car from going  off the trestle.  I used a Trex 2x2 for the
wooden edge rail.

Continuing maintenance includes tightening of nuts and bolts and treating exposed cut
ends to prevent deterioration of the wood.  Special tools that are helpful in
construction include: quick clamps, a 10 inch miter saw, long drill bits,  a 3/8 inch by
16 thread die and handle.
