Another Train/Science question has come up on my Science Forum: From: Dale 29/05/2002 11:27:03 Subject: trains post id: 51069 I have a question about trains. If you have one engine pulling some train carriages and you add another engine in series, do you double the pulling power? Or do you add a lot of power but not quite double? I'm stuck on the thought that either train would be pulling more weight than the other. Either the first is pulling the second and so the second is not effectively used OR the second is opulling the wieght behind it or the train in front is not required to pull as much. Can someone who understands physics help me with this?? Anyone with a good "scientific" answer? Click here to go straight to the thread, and click "reply", or if you post an answer here, I'll pass the info on. Or click here to go to the forum start page, and select "trains" as the topic. No need to register to reply to that forum. Thanks, if you can provide me with a good answer!
