Opened in 1835, the Thomas Viaduct was the first multiple-arch, stone railroad viaduct in the United States. The viaduct is composed of eight arches each with a clear span of about 58 feet. The viaduct has an overall length of 614 feet and a height of about 60 feet above the Patapsco River. Construction of the viaduct began in August of 1833, and a ceremony marking its completion was conducted on July 4, 1835. The viaduct was constructed for the Baltimore and Ohio (B&O) Railroad and is named in honor Philip E. Thomas, who served from 1827 to 1836 as the first president of the B&O.

The St. Charles Avenue Streetcar Line is the oldest surviving interurban-urban passenger rail transportation system in the United States. Originally incorporated as the New Orleans Carrollton Rail Road in 1833, service began in 1835. A variety of motive power had been used including horses, mules, overhead cable, steam engines, and ammonia engines before electrification in 1893. The 900-series cars presently in service were designed and built by the Perley A. Thomas Car Company of High Point, North Carolina, in 1923 to 1924.
For more than 174 years, the Canton Viaduct has stood as a dominating structure on the New England landscape. When completed in 1835, the slightly curved, granite masonry bridge - 615 feet long, 70 feet high, and 22 feet wide - carried a single track of the Boston and Providence Railroad, providing a critical link in the establishment of rail service between Boston and New York. In 1860, a second track was added. With few major alterations, the viaduct has continued to provide safe rail transportation to heavier and faster loads throughout the 20th century.
