I was afraid you are saying this. I doubt these will put pressure on the worm bearings and they are a bit 'in the way'.
Maybe a spring can do the same thing when it's glued at the correct spot replacing this metal thingy.

Does this mean that those metal spring "things" cannot be installed on the modified chassis?

I guess that springs installed in the chassis could replace the finger-type springs.
But for example I would not glue the bearing blocks to the chassis, or otherwise immobilize them.  Those bearing blocks should be able to float slightly (while held under some spring pressure).

They can be installed. Normally all three sides of that metal spring are sitting tight on the chassis. Now, due to the milling, the upper side of the metal spring is in the air and has no contact with the chassis because I needed to go down quite a bit so that the decoder fits nicely. I think a LokSound 5 micro is not that 'micro'.
I could try to shorten the sides of the metal spring.

Correct, glueing the blocks to the frame is not an option.

The "trick" is to turn the decoder upside down.  Rather than have the wire board on top, have it down.  Then you can take the end of the frame down just a bit more than the level of the bearing springs

Yeah, that's a good idea, but I'm not sure if this works for the A-unit.

So, a bit of progress...
It's good to have dozens of old Rapido style coupler springs lying around.
I shortened the springs and glued them onto the frame.



Next thing will be the housing for the headlights.

That should work well.

A little update...

The head lights:





The Erie Built is now ready and wrapped up in Kapton tape.

S**t, I think I fried the decoder!
While I wanted to test the second speaker under power something happened and I don't know what.
The loco is still running but very slowly but the sound is not coming up and the decoder gets quite warm.
You can still touch it but I think it's too much heat. There is a little humming as well.

D**n.
