The Battle of Aachen was a combat action of World War II, fought by American and German forces in and around Aachen, Germany, between 2–21 October 1944. The city had been incorporated into the Siegfried Line, the main defensive network on Germany's western border; the Allies had hoped to capture it quickly and advance into the industrialized Ruhr Basin. Although most of Aachen's civilian population was evacuated before the battle began, much of the city was destroyed and both sides suffered heavy losses. It was one of the largest urban battles fought by U.S. forces in World War II, and the first city on German soil to be captured by the Allies. The battle ended with a German surrender, but their tenacious defense significantly disrupted Allied plans for the advance into Germany.

The track gauge was 1,000 mm (3 ft 3+3⁄8 in), see Nordrhein-Westfalen. At times, the network also extended into Belgium and the Netherlands. At its maximum extent, its route length was 181.4 kilometres (112.7 mi) and its line length was 213.5 kilometres (132.7 mi). In 1914, it was the fourth largest tramway network in Germany.
