Took a rare mid-week day off "for the heck of it", and headed to the basement. I've been busy working on a bit of everything lately, mostly electrical.

Today I tore into the last few feet of benchwork to complete the branch on the upper level. This is a scene from the outskirts of Lewistown where the Milroy Secondary crosses the Kish Creek. On the far bank sits the Spanogle-Yeager mill with its spur. There will be a dam across the creek at this location.

On the PRR Middle Division in HO Scale, the Chief Engineer has delivered his Q4 construction report.

It was mentioned last week that construction goals for the quarter were not met, for the first time in several years. That sent shares spiraling by 8%. The root cause was a delay in bridge parts from a new supplier in Milwaukee [Walthers], causing various projects to be rescheduled.

Shares returned to normal upon revelation of numerous unexpected infrastructure upgrades including yard lighting and main power panel upgrades. The chief engineer is also pleased to report that yards at Enola, Harrisburg, and Altoona have been fully completed and are currently undergoing quality assurance testing.

The board of the Pennsylvania Railroad Middle Division in HO Scale may not be pleased when the chief engineer reports next week of the first miss of construction goals for a quarter, but hopefully that will be offset by the report that Altoona, Harrisburg, and Enola staging yards have been fully completed.

These yard areas have been deemed operational for some time, but the definition of operation required only one yard track per main line track, for run-through purposes.

The overall design calls for a total of 20 tracks. Trackwork was completed prior to the November open house; electrical work and detection was completed last week; and quality assurance testing was completed today.

The PRR Middle Division in HO Scale has a new main control panel, needed for the new PowerShield X and RRampmeter products discussed in previous blog posts.

The power flow for the command station and each boosters run parallel across the board, first passing through the RRampmeter and then the PowerShield X. Only one RRampmeter is currently installed, but as the photo shows, I have allotted space for one on each power bus. Alternatively, I can relocate the existing RRampmeter for troubleshooting purposes.

Per schedule, a two-track helix was completed. The outer track carries the Milroy Secondary from its junction with the Lewistown Secondary east to Menzies. The inner track carries the Pennsylvania Midland Railroadfrom northern staging to Allensville.
