 The railroad's experience with the locomotive was typical, and an indication of the fact that, though Fairlie had eliminated several problems of the conventional locomotive, he had introduced new ones of his own.At least one double Fairlie (pictured above) was built by the Mason Machine Works in Taunton, Massachusetts.Five narrow-gauge Fairlie Patent locomotives were built by Avonside of Bristol in the early 1870s for use by Canadian railways.
