Questions About Modeling NYSW in HO Scale

I need some info on a few units that i'm making. Here goes:


RRPX 78 what horns does it have, and where? And where's the bell?


NYSW 3618 What's a good color for the yellow? And what types of horns, and where.


That's it for now. i'll make this in the HO forum as well.

RRPX 78 has a 5 chime Nathan horn. The bell is mounted below and welded to the main deck almost directly under the engineer's seat.
