Alco C630 began production in 1965 which was a more powerful version of
the earlier C628 that had been in the company's catalog since 1963.
The new model could produce a respectable 3,000 horsepower using Alco's 251E prime mover.
By this point, most of Alco's orders came from loyal customers as it
became almost impossible for the manufacturer to either gain or earn back new customers with its troubled early prime movers.
Buyers of the C630 included Class I railroads Union Pacific, Southern
Pacific, Pennsylvania, Reading, Norfolk & Western, Atlantic Coast
Line, Louisville & Nashville, and the Chesapeake & Ohio.
Additionally, Canadian Pacific, Canadian National, and the Pacific Great
Eastern purchased examples of the M630 and C630M. By the time
production had ended in 1969 133 Alco C630s, C630Ms, and M630s had been
The Alco C630, and the Century line in general, offered the most
tractive effort of any locomotive in its class, even eclipsing the
Electro-Motive Division and General Electric. As such, railroads showed
real interest in the designs as many began to understand the value of
six-axle setups and the traction they provided. For instance, the C630
could produce 85,850 pounds of starting effort and 79,500 continuous
making them ideal for heavy drag service hauling freight such as coal
and ore. Through the end Alco continued to rely on General Electric to
supply it with internal components for its locomotives despite the fact
that GE was now a competitor.

At first railroads liked the six-axle Centuries very much considering
Alco no longer had significant reliability problems that plagued its
early designs. However, the longer railroads operated them the more
they noticed the significant wear the units produced on the track
structure. Weighing more than 200 tons (in comparison GE's U30C weighed
just 181.5 tons and EMD's SD35 180 tons both of which were in
production at around the same time) the Centuries were extremely heavy
beasts and could wreak havoc on right-of-way that was not laid with very
heavy rail with a solid support base (ties and ballast).
