I think you've already got it covered.

Dropping it down would really do wonders, even if you just bored out a few mm of ply it might be enough (thickness of the ply allowing).
In other news, I spent a few hours today getting DCC into the F45s I pictured in last week's WPF. I'd love to meet the person at Athearn who decided that having the couplers bolt directly onto the frame would be a good idea!

Having to remove them just to get the shell off really complicates what should be a very simple process, and reinstalling them is about the most fiddly thing I've ever had the misfortune of doing. I think I may now be a qualified neurosurgeon after doing 6 of the bloody things total. The decoder install itself was not easy either, as the "drop in" TCS K1D4 required a lot of troubleshooting to work. One loco worked first go, but the decoders wouldn't read on the others. In the end it came down to really poor contacts to the frame. I salvaged some of the copper terminals from the original DC boards and wedged some cut-up pieces inbetween the decoder terminals and the frame, with a small tab sticking out for easy removal with tweezers should the need arise.
All that aside, the model train gods have smiled upon me with these babies.

I didn't want to use TCS' "automatic" BEMF so was disappointed initially that their version of Torque Compensation did not seem as good as NCE's, but now that I've actually tried their BEMF I couldn't care less. Admittedly it is slightly noisier, but the performance is just stellar! I put the F45s in the same consist they'll be running in on my layout and they will happily play together without any speed table adjustments. As evidenced in the video below they'll pull 14 cars up a grade I calculated as 5.8%

(70mm rise over 1200mm) without any noticable loss of speed, and then run back down the other side without being pushed along by the load (the cowl body really allows for some really nice weighting compared to my other locos). I could see the BEMF in action as my Powercab showed the mA rising on the uphill then falling off on the downhill.

My only complaint on the performance side is that the headlights are dim on one of the locos, but it was doing that before the decoder install as well so it's probably just a loose lightbar. Future projects will be to fix this (tomorrow), add rooftop beacons (soon), and then sound (once I have an actual layout). Athearn also sell a version of these with sound pre-installed, so there's already room for a speaker in the frame - no milling required.
