This quarter was exciting for the division. Two open houses were held -- One in October for the NMRA MER regional convention, the second for The Model Railroad Open House in November.

Final grading (scenery) has been completed for half of the Lewistown Junction main line area -- specifically the stretch from Roundhouse Road crossing to the yardmaster's office. Roundhouse Road was modeled as a dirt road on the recommendation of a descendent of the local farm owner who recalls it was not  tarred and chipped until the 1960s. 

A first op session -- more of a "run" session -- was held on December 9th. John Frantz, Tom Jacobs, and Tedd Pounds put the Milroy Secondary through its paces and left a punch list for me to address.

The helix removal and nolix replacement will facilitate a design change for the Pennsylvania Midland, which interchanges with the Milroy Secondary at Reedsville. 

I've updated the backstory of the Pennsylvania Midland, adjusting the route of the southern end of the bridge line. It now goes directly to Cumberland rather than Hancock.

The Chief Engineer of the PRR Middle Division in HO Scale is pleased to report continued progress on the 43rd sub division.

This quarter, progress was made across all aspects of the railroad. Fascia control panels were added on the Milroy Secondary and existing panels were upgraded. Featuring Barrett Hill "Touch Toggles", turnouts are now controlled by touch on a schematic diagram which displays the current position of switches.

Scenery is well underway along Roundhouse Road, between the road crossing at LEWIS and the roundhouse at Lewistown Junction.

I'm pretty good with spatial relations and designing things in my head. Despite building a 24x32 railroad with a four track main line and yards terminating on corners, I haven't used CAD and everything has worked out just fine.

There's a helix on the Milroy Secondary (behind Milroy on  the upper level) and I had planned to use the airspace above it to represent Belleville, on my fictitious Pennsylvania Midland Railroad (which, in my world, took over the Kishacoquillas Valley Railroad).

The space directly above the helix had to be kept clear, but I had allowed 10 inches on two sides of the helix for Belleville, and much more on a third side. But when it came time to design, I just couldn't come up with something that met my needs. And then it happened...

The Belleville Epiphany!

The Chief Engineer of the PRR Middle Division in HO Scale is pleased to present its report for the second quarter of 2017.

Progress and been varied and slow, complicated by a short circuit (see separate blog), oral surgery, illness, and two inches of water in the basement as a result of a recent tropical storm!

Since last quarter, approximately half of the track has been laid in Lewistown yard.

Barrett Hill Touch Toggles have been implemented at two locations that feature single switches. Sort rails and card boxes have been installed for the Lewistown Yard crew, and dividers have been generated to assist in the sorting process. (See below.)
