Yes, it's located at the back, but I'm not sure what it really
is for. Part of a modified air-conditioner, maybe, but it doesn't
seem like a complete replacement for the air-conditioning itself,
or else the original air-conditioning pods in the front could have
been removed.
I have seen it (but never took it) running on routes 39, 2 and 354
before, and I wonder where will it go after being transferred to
AMDEP...
