Wabco E-2B-1

As early as the late 1940's, Wabco had a series of three chime "E-2B" airhorns available. The horns consisted of various E and B-series "pneuphonic" horn bells attached to a common manifold, with the two outer bells angled 3 degrees outward relative to the center bell. The E-2B horns never achieved much market penetration, but a few did find their way onto locomotives.

The E-2B-1 was probably the biggest seller of the line. It featured a large E-2 bell in the center, flanked by a B-7-21 and a B-7-25 bell. The combination of tones wasn't any particular musical chord, but was an handsome, deep sound nonetheless.

Early E-2B-1's used short and long B-6 horn bells instead of the B-7's . The horn's sound was reportedly the same in either case. Photos provided by Ed Kaspriske, Horns Inc.

Factory tuning was: 170Hz, 210Hz, and 255Hz

It is unlikely that any E-2B-1's survive on active locomotives, but thankfully several have been preserved in private collections.
