Alco C424's

What type of horn did these locomotives carry? I know it's a 3-Chime, Leslie I believe? Correct me if I'm wrong. Does anybody know what the exact models is?

The horn used on the C-424's was the Reading's standard for second-generation diesels, the Leslie "Supertyphon" S-3-2r. My guess is that they were the cheapest thing available, knowing the Reading. Are you planning to model? Which model are you planning to mount one on, if so.

I have the Atlas Conrail Alco C424 2492. This was a former Reading locomotive. So far I've had to change the fuel tank, add the rain gutters, and I need the right type of horn.

Thanks for the information.

Yep, that's the horn with the center bell reversed. Fairly easily available. The real challenge is the bracket to mount the horn on the forward cab wall. The proper bracket is found in Cal-Scale's 3-chime horn for an RS-3 that has long and short brackets in it. The short one is the one to use. I hafta look up those numbers for you.
