[PRCo] Trestle Construction

[Jim Holland]

Note the construction to this trestle and the wooden guards Not Only on 
the outside Edges but also between the tracks.       I haven't seen any 
other TrolleyCar system use such.

Most other systems appear to use a 2X4 as a guard  --  obviously bigger 
than that but Nothing in comparison to PRCo.       This guaranteed if 
there was a broken axle // derailment that the situation might be scary 
but the car Couldn't go over the edge unless the center of gravity was 
affected and the car tilted  *Severely*  --  and that is Highly 
Unlikely~!~!~!       PRCo was Highly Safety Conscious.
