One day during my time as a vollunteer with the Berkshire Scenic Railway in Massachusetts,We had to make a station stop at Stockbridge.I was the Brakeman and my engineer(I'll leave his name out)had to go real bad.The station was privately owned and was locked up tight.He made his way down the front of our SW8 #8619,and managed to squeeze himself inside one of the engine access doors,and close it behind himself to get some privacy.Keep in mind that we were towing a five car passenger train full of tourists and the engine was running when he went in.What ever he did his duty on I have no idea(his gloves?),but soon after I saw him emerge and fling a "package" off into the weeds.
