Actually, electric holding would retain whatever brake cylinder pressure your application called for unless and until you graduated it off, not only 10 lbs. Then only time a train would dump if it rolled was if it rolled in reverse and your C/R pulled the cord. In most cases we were able to leave the brakes released while standing except on steep grades (145 St upper comes to mind). Although only 5 D type units had roller bearings, old time BMT M/M operating D types would hold a light brake just in case there might be a roller bearing unit in the consist. |
