The only reason that they might have been though to be compatible is due to their similar physical appearance and dimensions. An knowledgeable railroad person would be able to see that they were incompatible due to the 2 different types of electric portions on the couplers. The BMT steels had a slide type of portion which did not advance automatically but had to be advanced by moving the cutting key to an advance position on the uncoupling valve after the iron and air coupling was done. The slide on the car from which the add was made advanced into the opposite slide pushing it out of the way and making the electrical connections. On the SIRT and later cars such as D types and R-1/9s, after the iron and air connections were made, both electric portions advance automatically and met each other making the electrical connections. The difference between the 2 types of portions is quite readily visible so it would be extremely easy to see that the SIRT cars and the steels would not be compatible at all not to mention that their propulsion systems were probably not designed to be compatible either. |
