CB&Q 173

Pictures are linked to a larger view, click on them.

I've got at e-bay two engines. CB&Q 173 got some weathering. Engine 187 will get older, too. But later. Now comes installing sound decoder.

But I got a problem with removing the hood. I took a few trials.



First step, the dynamic brake cover will get the speaker. But the speaker is bigger, so I had to mill. I worked on the cover and on the speaker!

At last, the speaker will snap in its place.

Speaker box and decoder doesn't fit in the place, Atlas has provided. So I removed the print board. Same procedure as with Kato's GP 35. Then I glued the decoder. The speaker would fit in the middle.

Then I soldered the wires to the decoder. With the spaker wires soldered, too, I could test run the engine.

You can see that I replaced the bulbs with white LEDs. The engine did run well and I could

install the hood. Here're two views with open dynamic brake cover. Still, you have a chance to adjust wires. The flywheels should run free!

And now the engine went into service:

Here's the first train, Extra 173 east. The extra has arrived at Third Street Industrial District and the first block with this destination is set out.
