No what I am referring to are the marker (red) lights on a tender or even the last diesel in Mu right in front of the coupled passenger or freight consist. Is thee any reason and/or rule that requires these to be lit.
No. They should be turned off. Those rear marker lights are only for when the locomotive, steam, electric or diesel, is running light, i.e. without a train, or if in helper/pusher service when coupled behind the caboose ( the locomotive then being the end of the train).
It seems to be no since they are not visible since the passenger/freight consist would bloke the view. But there might be a rule.
Nope. No rule.
