Dean:
I don't have any engines with sound in them. But I would bet that none of the 'accessories' in the lead engine have any effect on any other engine.

Correct. Only motion control and engine sound is affected on following locos.

I haven't installed in brass myself, but I do have a couple of locomotives that I'll be doing for a friend. I'm interested to test the results. I imagine it may attenuate the signal to some extent but without testing I can't say for certain.

You can remove "may" from that sentence. Brass most certainly will attenuate the signal. The $64,000 question is by how much. Of common metals, brass and copper are the two best for RF shielding. The size, shape, and thickness will play a role as these attributes determine the shielding resonance frequency. The closer the brass shell resonance frequency is to the LM RF signal frequency the more attenuation there will be. While the entire shell will have a specific resonant frequency, there will be points within the shell that have different resonance frequencies as well due to their cavity volume and shape i.e. the sand dome cavity will attenuate at a different frequency than the smoke box cavity. Try positioning the LM at different locations within the brass shell. You may find reception to be better at some locations and worse at others.

I guess the Hobbytown of Boston metal shell would act the same way?

If it is brass then I imagine it would.
Just guessing here, but considering the HC can communicate with a LM at a pretty substantial distance and given our relative closeness to the loco when operating I am going to go out on a limb and say there will likely be no issues. If the loco is 100' away at a big club layout or modular setup then maybe. Kevin will let us know how he fares.
