Strategic movement through Istanbul at level 3 - ??

[Pekkavilamoura]

In my current game Allies strat bombed Istanbul down to level 3 but I still can rail units through Istanbul. Does anyone have an explanation for that?

if you also control the railroad through the Caucasus (& Rostov or Stalingrad), then it might appear like you're moving through Istanbul still? Otherwise, not sure.

No, I don't have control of the rail line in Caucasus so I can't rail anything through Eastern Turkey.
Maybe the game is displaying some alternative route like a ferry over the Bosporus
I don't have any other explanation.
