The P Series are the most efficient and
economical line of locomotive air horns offered by Nathan.
P horns are constructed of sand cast aluminum bells and
manifolds, and have stainless steel diaphragms. The diaphragm
system in the P Series involves no metal-on-metal contact.
This results in bell castings that will never wear out.
The P horn is offered in single, dual, triple, four and
five chime configurations, and any combination of bells can be
easily reversed for multi-directional signaling ("R"
in the horn name denotes the following bell numbers being reversed).
Low and high mount manifolds are available for three and
five chime versions ("L" in the horn name denotes a
Low mount manifold). The most common configurations are
the P12345 (P5), P124 (P3), and P1234A5L (P5A) horns. We
also offer custom tuned P horns to suite your taste and give your
locomotive a distinct voice.
