retention tanks

Sometimes I just can't leave anything alone.

I had decided to stick with the Athearn SD40-2 frame as it is instead of searching out frames with the proper wheelbase just didn't seem like a fun idea. And then I had to do it.

I ordered some waste retention tanks. They're Railflyer Model Prototypes parts, and they are very nice. Here they are, in the raw...



And here's one of them, built up for the most part...



Now, CN added these to their locomotives as a way to prevent waste fuel products from leaking out onto the tracks, which would then find their way into the water supply. Good idea...unless you're me and you don't have the proper length frames. I now have parts that won't fit the current plan.

So, I'm off to find longer frames.
