I was able to cover the UP-Northwest in two phases. The first was a mid-day outbound run to Park Ridge where I could take photos out the back. The second was a morning run from Jefferson Park to Barrington, followed by an express run to Clybourn for video purposes. You can find the gallery of still photos here (mirror).
We begin with METRA F40PH-2 #165 blocking my view of LAKE ST tower upon departure of the CNW Station.
Passing under a classic CNW signal bridge on the 4-track trunk line between the UP-North line junction at Clybourn. Note how the former CNW used the left handed or European style of traffic flow. Also note the Automatic Train Stop inductor shoes as both the North and Northwest lines are ATS equipped.
CY tower at Clybourn still controls the split between the UP-North and Northwest lines as well as several interlockings on the UP-Northwest line.
The UP-Northwest Line crosses the METRA Milwaukee North line at grade at MAYFAIR interlocking. The tower here closed in the 1990's with control being passed to CY tower.
Here we see METRA F40PH-3 #149 passing under UP-NW line automatic signal bridge 120. the 3-track line operates under a 2+1 configuration between MAYFAIR and BARRINGTON with only the center track signaled for movements in both directions. While many of the signal bridges are original, the notable horizontal CNW signals have all been replaced with modern Darth Vader types.
Signal blocks are at 1 mile intervals until one gets past Des Plains.
METRA gallery cab car #8428 at Forest Park. Stations on the line take the form of a side platform and station building on the inbound local track (so that passengers can keep warm while waiting) and a island platform serving the express track and outbound local track.
To ride the express runs, one has to get up early. CTA Blue Line 2600-series #2652 departing Jefferson Park.
Jefferson Park station from the parking lot. Why the hell are all the towns near Chicago named "Park" when the areas all around them look urban?
