TLC has been publishing railroad history books since 1988. They offer a wide variety of titles covering many railroads and era and several geographical regions of the country. Their books are all printed on the heaviest 100-pound enameled paper and are fully illustrated with the best quality historical photos associated with their subjects. Their books generally contain a good deal of data and history, background, and information, in addition to the pictorial presentations. Some books are all color, others are black-and-white, and others have a mixture of color and b-&-w photos.
