We have talked about an expaned cab for a bunch of years now, which would make the engineers view to the rear much better. A redesign of the controls would be in order, making a conrol stand pedestal with all controls on it like the brakes, throttle and reverser. A new heater and some insulation to deaden the noise from the motor and transmission would becnice too.

Dynamat would be easy to install and not take up much room.

All this for an ugly small beast that beats up the rails!??  (I'm just being facetious here)

(BTW, Another argument for a two truck diesel?)

While widening 52's cab, how about adding a bit more headroom in that little loco?, am sure would be appreciated.

I have a better idea, at least for back-up movements. How about a big truck mirror mounted on the right side? Lots less hassle than trying to build out the cab side, extend the roof, raise the roof, move the control stand, move the brake valve, etc., etc.

I suggested this many, many years ago, but Jason nixed it on the grounds that people would come to rely on it. I've always thought that a picture of a steam locomotive with such a mirror would be of assistance in swaying him. I would have mentioned the X-2000's retract-at-high-speed mirror, but that would an argument in exactly the wrong direction. :D

Almost every diesel locomotive I've operated has a rear view mirror on the engineer's side.

Dynamat is a sound deadening product, often used in vehicles ...

I have this product in my car. Expectations have to be set properly when using this stuff. It's primarily intended to address sympathetic resonance, such as that arising from hollow body cavities and long, unsupported body panel spans, rather than primary resonance, i.e. the source of the sound. It accomplishes this primarily by just being heavy. Heavy objects have a lower resonant frequency and require more energy to resonate. For a given component, adding dynamat pushes either or both of these parameters outside the range of human detection.

You can pretty much tell if dynamat is going to help or not by just rapping on things with your knuckles. If you get a ping, twang, clang, boing, crash, or boom, slap some on. If you get a click or thud, skip it.

True sound deadening requires highly energy-absorbent materials, like carpet, dense foam, and fiberglass batting, along with complete mechanical isolation including air passageways. So that means no free hot air from the engine compartment in wintertime, or even really any ventilation of any kind.

Good technical points about sound dampening. One trivial point is that cab heat is provided by a hot water heater with two-speed fan. Luxury ;D

The former Sandia Labs '70s  Kline loco/car mover I ran at 2926 had a big, operator's truck side mirror that stuck way out.
We took it off the offset  cab side. It kept scraping containers, things along the narrow worksite.  :P
We didn't touch the separate little round mirror aimed down at the front coupler. It was handy.  ;)
