The railway drydock differs from the floating drydock and the graving dock or basin in its mechanical means for hoisting a vessel out of the water to a height above the highest tides, where it rests on a structure fixed to the ground. Vertical lifts are similar, but their platforms are not directly supported by the ground. In this description of the features of modern railway drydocks, it is noted that although such docks are sometimes perceived as outdated, the newer ones are, in fact, reliable facilities that are economical to both install and operate in the 100 to 6,000 ton capacity range, and that are highly durable in the harsh marine environment.
