General
Electric’s “Dash 7” locomotive line was introduced
as a replacement for the older “Universal-Series” of
the 60s and early 70s. “Dash 7” series
improvements included increased fuel efficiency, tractive effort
and reliability. The B23-7 was a direct replacement for the 2,250HP
U23B model.
The first units were produced for Conrail in September, 1977 (ironically,
3 months after the last U23B was delivered to Conrail). Production
continued
through 1984, with a total of 535 units built. Conrail was the
largest purchaser of the model, with a total fleet of 141 units. |
