I am looking for a recommendation for a Lionel (or MTH, Williams, Weaver) Santa Fe diesel road engine that can run without fear of electrical damage due to derailment when used with a stock 1033 Lionel transformer. From my reading on this site, it seems that any engine with modern electronics (i.e., circuit boards) needs to either use a modern transformer or needs a circuit breaker and, possibly, a diode added to the transformer (or a bit downstream in the wiring) when using a transformer like the 1033 in order to prevent damage to the electronics when the inevitable (at least in my case) derailment occurs. Is that a correct understanding?
If so, I've think identified one engine that fits the bill, the LIONEL 6-8265 Santa Fe SD-40 but it uses the blue and yellow warbonnet color scheme and I'd prefer the red and silver warbonnet (and I'm not interested in the F3 or any engine used specifically for passenger service). I'd prefer a road engine common in the 60s or 70s (in real life), like the SD-40, GP-38, or GP-60, and one that has an electronic horn. I've spent a bit of time on eBay looking at engines for sale and there doesn't seem to be much beyond 6-8265 that fits my criteria. Apart from the color scheme, I like the features of the 6-8265, but I'm wondering if Lionel or anyone else made a similar engine using the red warbonnet paint scheme.
