An engineer for BNSF Railway Co. said his railway's coal trains average 120-125 cars. Steven Forsberg a BNSF spokesman put the average at 110 to 120. But whats the MAXIMUM amount of rail cars that can be hooked together? Do you know what the MAXIMUM amount is ???

I would imagine that it COMPLETELY depends on how many locomotives are attached.
My guess:250

Power has nothing to do with the length of the train. They can add on as many locomotives as needed to the front and back of the train in order to pull it. 250 cars maybe yes then maybe no. - Millet

Isn’t it the more to do with the time it takes a train to go through a railroad crossing? I thought that there was a time limit on train crossings rather than a limit on boxcars. Let's say 10 minutes.

Karl, thanks for your answer. However, it has nothing to do with how long it takes to pass through a railroad crossing. - Millet

In looking for an answer to Millet's question, I saw two possible answers. One, the load limit of the couplings. Two, the length of the sidings (side rails to park slower trains to let others pass). I would have to go with number 2 for my answer. I guess side rails would vary from line to line, but, from what I read, around 120 cars appears to be the norm.

Congratulations Ned - for supplying the correct answer, it is the length of sidings along the route. . Dispatchers put a train in a siding to allow another train to pass, but you can't put a train in a siding if it is longer than the siding. On a route between Southern California and Chicago, BNSF runs 10,000 foot trains, because sidings aren't an issue. This run has two tracks almost all the why from California to Chicago. - Millet

If the answer is here, I didn't quite see it, but it does confirm what I suspected: the drawbar strength is the limited factor.

Thanks Patty & Millet. I was born, raised, and now live, within 300 yards of a railroad. Not that that was how I knew the answer, I looked it up on the web!

Ned that is exactly where I got the question. Out of the Rocky Mountain News, while eating breakfast and reading that paper. The Rocky Mountain News, is the local paper. - Millet
