The Central Uruguay Railway (CUR) was one of the five original rail systems in Uruguay. The other four were the Midland Uruguay Railway Co., the North Western of Uruguay, the Uruguay Northern, and the Uruguay East Coast Railway. CUR, including its leased and worked lines, was considered the most important system.[1] It controlled about 1,560 kilometres (970 miles) of track. The system operated four sections: the Central Uruguay Railway Original Line (including the Northeastern Line), 436 km (271 miles); the Northern Extension Railway, 298 km (185 miles); the Eastern Extension Railway, 501 km (311 miles); and the Western Extension Railway, 340 km (211 miles).[2]
