They never made it to Chicago, New York or Los Angeles to be painted on that's why,l.o.l

Thank you for watching, Robert!

1. Back then, most railroads had 3 or even 5 man crews. With that many people riding on the head end, the lead unit would often be crammed which is why most of the time, half of the crew would ride in the second unit. 2. The mid-train units, or “Slaves” as Southern/NS called them early on, were equipped with radio control so that they could be operated by the “Master” unit (lead locomotive) on the train. Back then, the radio equipment was too large to fit inside the nose of a locomotive or on top of a cab, so Southern built these special radio boxcars that housed all the gear inside. When the boxcar was MU’d to a mid-train unit, the engineer on the lead locomotive could simply “dial in” on whatever radio frequency the boxcar and mid-train unit were using and control them from the head end. Radio cars go waaaaay back on the Southern… The early 1960s, I believe. Most other railroads came up with creative ways to do DPUs without having to use a boxcar with all the gear inside. Instead, railroads like Santa Fe, Union Pacific, and Southern Pacific would order specific units with “Snoot” or extended noses to house all the radio gear. If you look at pictures of some those locomotives from the 70s-90s, you will see a lot of extra antennas on top of the cab. That’s because of the radio equipment inside the nose of the unit, likely an SD40-2. Also, side note, but back then, the mid-train units were not called DPUs on any railroad. Instead, they were called “Locotrol” Units, named after the type of radio equipment inside it. Hope this helps! Thanks for watching. -Drayton

Thank you! It helps a lot!
