Description
This tunnel is the eastern of two bores dug in 1929, when the Missouri Pacific Railroad was adding a second parallel track on their busy St. Louis to Kansas City mainline and sought to reduce gradient, curvature, and route miles. The original right of way, built in 1853, crested the watershed boundary between the Meramec and Missouri Rivers here, and was at the top of an ascending grade from both directions on the railroad. In 1845, with the anticipation of the railroad bringing travelers through the area, New York businessman Daniel Gray built a hotel on the ridge, known at the time as "Point L'Abaddie", near where the railroad was surveyed to be built. His name was given to the depot and the new settlement: 'Gray's Summit'. On December 22, 1982, all Missouri Pacific properties were acquired by the Union Pacific Railroad Company, which has continued regular rail service through the tunnel.Facts

Here is an old photograph, regional map, and street plan of the old town of Gray Summit, I've found no date, but I'll guess around 1900. The city map reveals a small spur track leaving the railroad east of the townsite, where limestone was quarried and shipped out by rail.
