>>971345Relatively few good pictures of these cars exist in their original form.
A fun fact, BS1 is the only bi-directional two cab unit that can be driven from both cabs, even though even with this unit, the rear cab lacks things like light switches and sanding pedals, but the thing has a proper controller circuit.
Also, the thing found lacking is a proper large floodlight, originally it had only one light at both end and a removable red glass to make the rear light red.
