Texas Railroad History - Tower 4 - Dalhart

A Crossing of the Chicago, Rock Island and Pacific Railroad and the Ft. Worth and Denver Railway

This photo of Tower 4 was taken by John W Barriger III in the 1930s from the rear of his business car as his train proceeded west on the Rock Island Golden State Route. The Rock Island station is visible in the distance. The FW&D crosses behind the tower, left toward Denver and right toward Ft. Worth. (John W Barriger III National Railroad Library)

In 1901, the Chicago, Rock Island & Pacific (CRI&P) Railroad built southwest across the Texas panhandle from Liberal, Kansas toward Tucumcari, New Mexico, crossing the Ft. Worth & Denver (FW&D) Railway, which had built through the area in 1888. The crossing location was named "Denrock", a hybrid of the two railroads' names. When the Post Office later rejected this name, the new settlement was named Dalhart for the two counties, Dallam and Hartley, whose county line the town straddles. Served by two major railroads, the town quickly outgrew other settlements in the region and became the county seat of Dallam County.

Tower 4 at Dalhart was one of the first railroad towers in the state, authorized for operation with a 28-function mechanical interlocking plant on November 28, 1902. The railroads crossed in an "X" pattern just north of what became the Dalhart central business district. Tower 4 was originally located on the north side of the X, less than a mile from both depots. The proximity of the crossing diamond to downtown Dalhart created a major traffic congestion and safety problem. The main street through downtown, Denrock Ave., crossed both lines very close to the diamond; waiting trains blocked this and other grade crossings. In 1939, the Texas Highway Department and the City of Dalhart began a major grade separation construction project that would tunnel Denrock Ave. underneath the tracks and also create a tunnel for US Highway 87 along the alignment for Pine Street. The widening of Denrock Ave. through the tunnel required Tower 4 to be relocated to the east side of the crossing. A series of temporary modifications to the interlocker was approved by the Railroad Commission of Texas to facilitate continuous operations during the various phases of construction. Today, the FW&D line is a main route of BNSF while Union Pacific operates the former Rock Island "Golden State Route".

Historic Photos of Tower 4

Above Left: One of the earliest photos shows downtown Dalhart still in the horse and buggy days. At the edge of the tree line on the right side of the photo, at the far end of the street, Tower 4 is barely visible. Above Right and Below: Early model cars and dirt streets are apparent with Tower 4 clearly visible in the distance.

Above: Facing northeast, the concrete and iron railings adjacent to the crossing diamond serve to prevent railroad workers from falling into the approaches to the highway tunnels beneath the rail junction at the site of Tower 4. The former Rock Island depot is visible in the distance as a two-story yellow building to the right of the large tree. (Jim King photo c.1998)
