When the steels were first delivered they lacked MU door control and the C/R button board only controlled the doors in its own cars. When the BMT unitized the cars into B units, the added MUDC but since the there was no room on the slides of the drawheads for additional contacts, 9 point jumpers had to be used with receptacles for them in order to have MUDC in a complete train. What did surprise me is that even though the D types and the Multis had the more modern electric portions like the R-1/9s, the door circuits were still in jumpers instead of in the electric portions. |
