USSR electric trains have a similar design feature: it consists of two kinds of cars, one has pantograph and the other has some other equipment which makes it hum when it stands still on the station.
And they're always interleaved like this: chphphphphc
(c - car with a cabin, p - car with pantograph, h - hummy car)
I wonder if it ever caused logistical problems when assembling trains from cars. Probably not since they are visually different and not sensitive to flipping.
P. S. And toilets? You only had two - one in each cabin cars.
