The most recent (2006) Metra weekday boarding count (from RTAMS) indicates Hubbard Woods had 371 weekday boardings, the latest number in a decline from the highest recorded weekday boarding count in the RTAMS system, 502 riders in 1987. I imagine that the downward trend of ridership has continued since 2006, but even going by the eight-year-old numbers, let's compare the weekday boardings at Hubbard Woods with the other stations on the UP-N which don't have agents:
Kenosha: 431
Winthrop Harbor: 79
Zion: 152
North Chicago: 191
Fort Sheridan: 279
Highwood: 279
Ravinia: 332
Ravinia Park: No Data!
Braeside: 341
Hubbard Woods: 371
Indian Hill: 362
Evanston Main: 869
Rogers Park: 1,176
Ravenswood: 1,940
Clybourn: 697
The removal of the agent at Hubbard Woods seems to be a sound decision based on its weekday boarding figures compared with those of other agent-less stations on the UP-N line.
That old car might be worth money!
