N&W Bridges -- Guidance Sought for a Unique N&W Prototype

[NW Modeling List]

Bill, 
     While not a N&W bridge, the Reading‘s Philadelphia Line bridge over the Lehigh River in Bethlehem, PA. had a span replaced in the mid-1960’s with a new one that had a switch fully on the bridge that allowed the Lehigh Valley railroad to connect with the Central Railroad of New Jersey and gain access to the Allentown yard. This happened because both the CNJ and the Lehigh Valley had reached an agreement to combine trackage up the Lehigh River to reduce maintenance costs.
       The Delaware & Hudson also used the bridge to gain access to the ex-Lehigh Valley line under Conrail(I don’t know if that makes it a bridge used by the N&W, since they owned the D&H at the time?) The switch has since been removed, but NS trains still use the connection to get back and forth between the Allentown Yard and the ex-LV mainline.

While not N&W, when space limitations required “creative solutions”, putting points on a bridge was common.  I suspect the tight quarters in N&W’s hollers often resulted in cramming bridges, switches, wyes, etc. into places that drove the engineering departments nuts.

It features the rugged terrain that covered much of the N&W service area, including numerous tunnels having the effect of expanding the visual size of the layout.  A prominent feature is a stream crossing the middle of the layout.  The numerous bridges crossing this stream are another visual interest feature of the layout.  On one side of the stream, a large coal mining complex located on a plateau surrounded by steep mountain terrain pays tribute to the N&W's historical association with the coal mining industry.  Recently I decided to locate a steam engine servicing area on the “other side” of the stream (in lieu of a planned community setting).  The steam engine serving center will include a scale 110’ turntable, three-stall roundhouse, and various other facilities.  This area will provide a much more interesting active area of interest than the originally planned community with a siding but little else by way of active operational potential.

Positioning of those facilities would also dictate the location of the rest of the facilities and the track within the service area.  As it turned out, the most problematic issue involved the location of the track crossing the stream to enter this area.  That bridge was positioned such that I could not bring a 22” radius turn into proper alignment with the turntable without locating a turnout on the bridge itself.    The bridge is actually quite interesting in design and execution.

If there was no similar prototypical bridge on the N&W system, I will nevertheless be compelled to use this bridge to access the turntable within the steam engine serving area, but it would be nice to know whether this solution has any forebear in the prototypical world is wholly a function of necessity and the modeler’s imagination.
