(Ooh a Ditch light turn on) NB Intermodal with a EMD leader turning on its ditch lights at Spaulding

This was the northbound that we saw after the other northbound that we had to wait for at the crossing. We heard this one over our scanners but we didn't think this EMD leader would turn on its ditch lights at the last moment. I originally did see it with its ditch lights on and then it turned off for only a few minutes before when it reached us it turned it on. not sure what the crew was thinking. I guess they understood what we were doing there and decided to give us a cool show.
