Louis:
Attached is a cleaned up and slightly cropped version of the image. Given the information you have provided and using March and November 1914 public timetables (the only 1914 ones I have), the train is most likely No. 51, the Northern Pacific Express, which
departed Chicago at 9:30 a.m., Aurora at 10:28 and ran non-stop through Shabbona to Rochelle, arriving at 11:40 a.m., and finally reaching Minneapolis at 10:55 p.m. No. 51 and its eastbound/southbound counterpart, No. 52, the
Atlantic Express, were electric lighted and equipped as follows: "Between Chicago, St. Paul and Minneapolis, standard drawing-room and tourist sleeping cars, first-class high-back-seat coach and smoker-coach. Chicago to St. Paul and Minneapolis,
observation sleeping car, chair car and dining car." Oddly, that appears to be two different though similar equipment listings for the same train. Whatever the case, Q No. 51 connected at St. Paul with NP No. 3, which departed St. Paul at 10:30 for Seattle
and Tacoma, connecting at Spokane with SP&S No. 3 for Portland. Leaving Chicago on Monday morning at 9:30, one arrived in Seattle at 11:00 Thursday morning. On the through train equipment listing, the following is shown: "Chicago to Seattle, Tacoma and
Portland, through standard drawing-room and tourist sleeping cars to Portland, connecting en route with through standard and tourist sleeping cars to Seattle and Tacoma, coaches, smoking car and dining car. Chicago to St. Paul and Minneapolis, observation,
standard drawing-room and tourist sleeping cars, chair car and dining car."
The only other westbound/northbound train through Shabbona near mid-day was daily-except-Sunday all-stops local No. 19 which left Chicago at 8:00 a.m. and reached Shabbona at10:47 and terminated at, of all unlikely places, Flag Center, at 11:31 a.m. Its
eastbound/southbound counterpart was No. 22, leaving Flag Center at 5:20 p.m. and reaching Chicago at 9:00 p.m.
