I want to install a inline fuse to protect modern engine electronics using a postwar transformer but not sure what amperage fuse would be sufficient. Any help would be appreciated.

10 amp fast-blow is the most recommended here. The fuse will only protect the transformer and wiring, though. A TVS diode is needed to protect the electronics. If you do a search, you will many threads on the subject.

Thanks for the help.
Here is one thread on the subject. If you have just one line, I'd be glad to send you one.
The best protection I’ve found for a fast breaker is the PSX-AC which you can buy at Charles Ro. Adding a TVS diode will cover it all for protection. It’s important to trip fast so you don’t melt wires inside the cars, engines, etc. And don’t weld wheels to the rails.
