Many years ago, as a reporter/editor for a suburban newspaper chain in the Chicago area, I got an opportunity to ride along with Metra officials on an inspection tour. The day began with a hi-rail inspection of Metra Electric, followed by a bus ride to Aurora (this was before the current Aurora terminal was opened) and the highlight of the day, a ride in a BN (this was before BNSF, I told you it was a long time ago) business car on the back of a Metra/BN commuter train. After lunch in the business car (I believe it was the Missouri River), we viewed the condition of the BN tracks and stations from the business car. Since Chicago area commuter trains operate with the locomotive on the "suburban" end of the train. The business car was located behind the locomotive. This was the first and only time I've witnessed such an operation. And, man, did I have a great job, a full day of railfanning and I got paid for it.
