Lewistown, like dozens of other locales across the Pennsylvania Railroad system, had a track scale for weighing of cars loaded with bulk commodities. In the case of Lewistown, the predominant cargo was limestone from the multiple quarries on the Milroy Secondary.

This article follows my build of the Lewistown scale house and its gauntlet track. As an aside, this project will be presented towards my NMRA AP certificate in Civil Engineering which requires three scratch built track items. This project will address two: gauntlet switch and gauntlet track.

The Chief Engineer reports much better progress this quarter, especially in the Lewistown Yard. Ballast has been completed between the tracks, on the tracks of the main line arrival/departure yard, and the branch arrival/departure tracks.

In the image above, the four tracks at upper left are the main line tracks. In the distance above center is the main line arrival departure yard. Left to right, then, are 11 classification tracks. They have not been ballasted yet. Then two branch arrival/departure tracks, and finally a thoroughfare track.

The Chief Engineer reports substantial progress this quarter.

All QC issues previously reported on the Milroy Secondary have been remediated. The secondary is ready for another QC session.

All switch machines have been installed in the Lewistown Yard and are ready for cabling to be installed. There is one troublesome switch machine and two shorts remaining to be remedied.

 

The Chief Engineer reports mixed progress this quarter.

All QC issues with trackwork and turnouts in the Lewistown Yard have been resolved. In one very frustrating scenario, a diverging route was generating constant shorts, with no visible sign of cause. Out of frustration, the rail was removed from the ties and manually replaced. Fixed the issue. Go figure!

PRR Eastern Region Drawing

The PRR Middle Division in HO Scale has finally found a software solution to meet its needs!

Over the years, I've developed three specific needs for computer aided design (CAD) applications. However, each need previously required its own unique software, each with accompanying learning curves.

For my NMRA AP in Civil Engineering, I need to create a drawing of my layout. Heck, I want one regardless of the AP. I've been a registered user of 3rd PlanIt and have tried other free demos as well as open source offerings. I found them all clunky and with a cliff of a learning curve.
