Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A drag freight is a slow, high-tonnage railroad train, often carrying commodities such as coal or ore. Compared to Fast freight trains, drag freight trains have a very low power-to-weight ratio, making them somewhat unpredictable on steep grades or hilly routes. This causes many dispatchers to be extremely conservative with how they handle drag freights, especially when they share lines with higher priority fast freights and passenger trains. In the mid-20th century, large locomotives such as 2-10-2s were typically used for drag freight operations.
