Built from 1912 to 1913, Lambton served as mechanical and freight facilities. It also had a roundhouse facility from 1913 to 1960. This infrastructure was replaced by an intermodal freight facility which transferred freight between truck and train, the site of which is now a Walmart store.
Around the mid-1960s an employee train shuttle works from Lambton over to the Toronto Yard in Agincourt.[1]
