Some of the trains on the Golden Lake line are known as “mixed” trains. These are essentially freight trains with one or more passenger cars added to the rear. In this photograph a mixed train is entering the Pembroke yard from Golden Lake. Mixed trains can provide a very rough ride for passengers when passengers cars are attached to the end of a long train of freight cars. When the engine slows down or accelerates the slack action of the couplings can create a jerking motion at the end, and the engineer has to be careful in the way he handles his train to minimize the discomfort to his passengers.
