ASF's Keystone Draft Gears
ASF-Keystone Locomotive Draft Gears have been
the standard of the industry for more than 30 years. Utilizing
our Key-GardTM elastomer, our gears provide superior buff and
daft protection in even the heaviest locomotive applications.
Our locomotive draft gears are used in freight switchers (485
Series) and road units (390 / 391 Series). They are also used
in passenger service (488 and 489 series). The 390/391 series
gears are available with heavy duty alignment control for anti-jackknifing
protection.
