Rotary snow plow power units

[TinMan2000]

I am trying to find some top views of the power units used in rotary plow service such as the "F" b units used by the BN/BNSF. Mainly the fan area. Side views show sheet metal sloping towards the fan with hinged doors on the sides, but none show if there is any sheet metal covering the tops of the fans and if any hinged doors are used on the top.
TIA

I didn't find any good views, but some hints here:

Thank you! These were exactly what the type of shots that I needed, including the A unit, which is probably of SP&S heritage. You also opened my eyes to a few more web sites I was not aware of.
Again, thank you. I knew this group has a wealth of knowledge and resources.
