A rail line was built through the Leyner area in the early 1870s by the Denver & Boulder Valley Railroad, connecting Boulder and Brighton. The D&BV was acquired by the Union Pacific Railroad in 1898.^[5] Leyner does not appear on topographic maps until 1951, and it was adjacent to a siding, indicating that it was probably a railway station at some point in history.^[6]

The rail line has been owned since 2009 by the Regional Transportation District.^[7]
