This large ungainly B&O locomotive was designed by Ross Winans in 1948. The engineer's cabs location was prompted by the firebox design, so large that there was no room for a conventional cab. These locomotives suffered from the lack of crew considerations and also communications but were known for their power. They worked well into the late 1900s when they were replaced by larger conventional locomotives. This one is located at the excellent B&O museum in Baltimore.
