Belen has the only Harvey House Museum in New Mexico. The Santa Fe railroad arrived in Belen in 1880, when Belen was a small farming community. For the next 25 years, there was little train traffic through Belen, because the main rail line went west from Albuquerque. In 1908, the railroad opened a new line that avoided the steep grades over Raton Pass. This new line was the Belen cut-off, and it routed many more trains through Belen. Shortly after the new development, Belen began to bustle.
