Daniel: IAW my references the 2613-14-16 came in sets with either the 226, 263 or 763 loco. Note that the 2613 series came in state green or blue . The 613-14-16 which is the same car except it does not have the "box" couplers came with many more engines but still included the 763. The interesting thing is that the 613 series did NOT come in green but it did come in terra cotta / cream and red / light red as well as the blue / silver Blue Comet livery. Both the 613 and the 2613 series in blue/silver were nicknamed the O' gauge Blue Comet when pulled by the blue 263E loco. So with your 763 you could pull Green, Terra Cotta, Light Red, or Blue passenger cars depending on whether you went with the 613 or 2613 series and both look about the same except for the couplers.
Of course regardless of what its pulling the 763E is MAGNIFICENT!
Best Regards, Don McErlean
