During the first trip, I caught a two engine train that looked like a container train:
But then the train changed from container cars to the following type of car:
The articulated cars must be efficient because of reduced rolling resistance and uniform cross section (lower wind disturbance) because it was a rather long train for just two engines Or else the BNSF uses a lot bigger engine on this route than they do on the CB&Q route. And/or, the SantaFe route across Illinois is flatter than the CB&Q route. But now that I'm thinking about it, maybe CB&Q is now using just two engines and I haven't noticed.
The pictures I took during my second trip had a train parked on the bridge. The red lettering on the end-unit just beyond the end of the bridge is "AUTO-MAX." So that confirms my auto carrier assumption. By the time I went on this second trip, I had bought a new SLR camera. So I can now digitally zoom in by cropping the picture before I upload it. The following is from the above short span image:
I also included a bridge joint since picture height is not an issue. It is nice to know that you can easily "count rivets" with just the normal resolution of the camera. Note that the car is empty. I was wondering if the cars are filled with Asian imports when they are being back hauled to midwestern car factories. Or maybe the imports are off-loaded before they get this close to town. I have seen a "car import" yard in the Chicago area, but now I can't remember where.
The reporting marks were AOK followed by a 6-digit number. I can't include an image of one because every one had a bridge beam obstructing some part of the mark, even in the long span picture.
When the train started, the remainder of the train was car carriers. I could not see the front of the train to tell if it had container cars up front like the previous train had.
One reason why BNSF may switch these articulated-car trains to the SantaFe route is because:
- they are long, an 8000-foot limit
- there are few grade crossings because it follows the canal
- there is no commuter traffic because the train station is on the Alton tracks
- to be researched: larger, more efficient intermodal yards
Conversely, the CB&Q route has heavy commuter traffic and a lot of grade crossings in the Western Suburbs.
