Decoder for Bachmann 2-4-2T

It depends on how 'twitchy' the decoder is?

Two things will decide this:
How much current is required to start the motor turning under load.
What the stall-current of the motor / drive-chain is.

If the instantaneous starting current is too high for the decoder, it will (hopefully) shutdown.. - Or (worst-case) let out the magic-smoke.
If the stall-current is too high, hopefully, the decoder shuts down, to protect itself.

Personally, I would go for something with a higher rating..
