Block Instruments

I wonder if anybody has produced the semblance of block
instruments (Clear / Blocked / Train On) by using cheap radio
control servos to swing the pointer?
Also, would these servos move fast enough to strike a bell
repeatedly (Train running away in wrong direction?)

No, but it's an interesting idea.
A servo can certainly move fast enough to strike a bell repeatedly, depends how fast.

Then a simple astable with a variable mark-space ration (NE555?) would be all that is needed at the sending end to simulate the output of a RC RX to drive the servo.
