Very loudly

Must say I’m pleased with my Nathan train horns. Just finished installing them. Haven’t used them on the road yet but can’t wait! I live on top of a ridge at the end of a cul-de-sac and I pulled the handle back and it echo all threw the valley below.

train whistle

I put your air valve on my train, now the whistle sounds good. Everyone loves he handle. Was a big hit in the 4th of July parade. Very easy to mount. Made well, heavy duty. No plastic.
