The A-2 was a single-note horn used primarily on switchers. It had both a long bell and
short bell version (15 in. and 11-5/32 in. respectively). When used singly, the long bell
was generally the one used. Wabco also produced a two-chime AA-2 horn
which combined a long and short bell A-2 on a common manifold. The A-2 was fairly common
on Alco switchers of many railroads.
|
Factory tuning was: D for the long bell, G for the short bell |
Wabtec was still offering the A-2 as of 2001, but no large railroads are known
to have purchased any. As with all Wabco horns, A-2's are rare to find in service today.
They may still be found on older switchers or museum locomotives.
