Roadway Templates

In Layout Design Process 6 - Railroad Modeling I discussed the variety of prototype railroads Right of Way Maps used to identify right of way information: track diagrams, rail and ballast information, drainage, superelevation and grade line, bridge and building, and signal and communications information. 
 
It is now time to get into the details so that the WWSL Maintenance of Way track gangs can start  construction.

Modeling Information

If you are a Railroad Modeler and you are basing your layout roadway on how the prototype does it, then the following reference pages will help you figure out railroad engineering.

4.1.0 Right of Way discusses how railroads obtain their rights of way and how they document their right of way information.

4.1.1 Roadway discusses roadway engineering and construction, and the use of common standards used by railroads to communicate roadway standards based on their unique operational needs. This page also communicates the roadway standards to be used by the WWSL.

4.1.1.1 Roadbed discusses the geographic issues in roadbed engineering and construction, specifically roadbed construction specifications.

4.1.1.2 Embankments discusses roadway engineering and construction of embankments.

4.1.1.3 Cuts and Fills discusses roadway engineering and construction of cuts and fills.   

4.1.1.4 Drainage discusses the importance of drainage to roadway maintenance and the engineering and construction of cuts and fills.

The WWSL

The WWSL is going to use prototype right of way practices whenever practical. The WWSL is going to use The Milwaukee Roads right of way standard as it applies to electrified lines on the 1st (Northern) Division. 

The WWSL roadway standard will be based on the Union Pacific Common Standards - because that standard was the only consistant regional Class 1 roadway standard I had available for use. 

The WWSL engineering department has identified 15 roadway types that can used on the WWSL right of way. While that may seem excessive to railroad modeling, it does give me some prototype modeling latitude on the WWSL. See 4.2.11 Roadway Modeling Techniques for more details.

The Northern Pacific 16th Sub-Division at Brady, Wa. will be built to Northern Pacific Branch Line practices. See 4.2.11.14 Modeling Technique for Northern Pacific Branch Line for additional details.

The Milwaukee Road / Union Pacific 16th Sub-Division will be built to Union Pacific Branch Line practices. See 4.2.11.15 Modeling Technique for Milwaukee Road / Union Pacific Branch Line for additional details.

The WWSL will include in its modeling efforts drainage and other roadway details (such as hand and motor car set-offs, rail racks, etc), and appropriate signage.

I am going to build a right of way test section to develop and refine the techniques I will have to use during WWSL roadway construction. Those techniques will include putting down layout lines, determining tie spacing, putting down straight and curved track , developing turnout upgrade techniques, and practicing foam roadbed hot wire cutting to name a few new skills.
