Thomas & Friends Circuit Board Thing-And it's Purpose.

[T-95]

Hi,

Does anybody know what those circuit boards screwed on the cabs of the engines are for? And would it do any harm if these were removed and replaced with a decoder if one decides to go DCC?

Dear T,
The circuit board makes the eyes move at a constant speed regardless of speed.
Have fun!

     Yes, without the circuit board, the eyes would move as fast as the loco.

my eyes adjust with the spped of the loco if it goes slow they go slow too same with fast its like that for all my models

[ZeldaTheSwordsman]

They don't go as fast as the wheels,though.'course,I plan to alter my models
to have radio-controlled eyes.

[T-95]

Oooh-how do you do that?

Computer Chip?

A few companies make an RC DCC system, where the throttle is wireless. If the eyes are set to say Function 4, when you press F-4 it will cause the eyes to spin, pressing again turns them off. To have an RC control just for the eyes will demand a lot of space.
