I would recommend a more "electronics friendly" transformer, something with fast tripping breakers. I use a ZW-C on my newer items.

Too many people keep making this incorrect assumption. Modern transformers won’t prevent damage to a locomotive’s electronics as a result of high-voltage transient spikes.

The circuit breaker is designed to protect the transformer, not the train, and do so when there is a surge in current, not a transient voltage spike.

To protect the locomotive, you need a TVS diode installed. It would be best closest to the electronics it is protecting, inside the locomotive, but for simplicity’s sake, most put the TVS between the transformer and the track connection.

Here’s a good thread from a few years ago, but this topic has been addressed often since then on the forum.
