Hi Chris,
I did just this with my #4559 about 18 months ago. I built stretched 2 wheel
"Super bogies" that support the ends of adjacent cars. And, since the train
end (tail) has the same s-bogie, I fashioned a tailcap that continues the
train streamlining **plus** it has a fifth cargo bay. For this I built a pod
with computer/electronic door motifs. On my raillines, these mobile tele-
communications platforms are hauled by the trains to augment the satellite
network and generate revenue (now there's creative marketing). The stretch
work continued forward with the loco lengthened by a stud.
