Marijuana withdrawal can be more intense than people sometimes realize. While heavy, chronic users may begin to exhibit signs of depression, many users experience insomnia, anxiousness, and irritability.
A New Era. Although diesel locomotives first came to American railroads in the 1920s, their use was confined to switch engines, and later to passenger train locomotives. It wasn't until 1940 that the Electro Motive Division of General Motors (EMD) demonstrated that diesels could practically replace steam locomotives in heavy-duty service.
The diesel motors on a locomotive actually produce 3600-6000 HP based on the model and age. I'll have to talk to the locomotive repair shop at work, and I can get to you on how much actual HP goes to the wheels. I do kmnow that each wheel is driven by an electric motor and they are huge.
