The U33C was General Electric's first six-motored model to sport a noticeably flared rear radiator; needed to handle the unit's 3,300 horsepower. The model sold relatively well for GE with some 375 units out-shopped by the time production ended in 1975. Southern Pacific purchased the most, taking possession of 212 units between 1969 and 1975 ...

The GE U33C is a 6-axle diesel-electric locomotive built by GE Transportation Systems between January 1968 and January 1975. [1] 375 examples of this locomotive were built for 11 North American railroads and one construction contractor. 5701 was wrecked and never wore the BN Cascade Green.

Following its Alco C-628 (6300–6314) and C-630 (6315–6329) buys, PRR ordered 15 C-636s delivered to PC in early 1968. Pennsy’s GE six-axle U-boat roster included U25Cs (6500–6519), U28Cs (6520–6534), and U30Cs (6535–6539).

All original locos were painted in the lightning stripe scheme, and #758 was the only U33C to receive the all blue and yellow nose stripes. The ex-Conrail locomotives retained their Conrail blue for some time.

The 3,300 hp U33B arrived in December 1966, while the U33C did not follow until 1968. The first U28s were visually similar to the U25, but changes such as the shortened front hood were only introduced later. The U30B and U30C were able to reach a total of almost 900 units because EMD's production was at capacity. The U33C also made it to 375 units.

2009年1月23日 · EMD’s SD45 had a 20 cylinder 645, while the GE U36C and Alco C636 offerings were able to stick with the same 16 cylinders as their 3000hp counterparts. GE also had the in-between U33C. Just wondering why the U30C, and later C30-7, were more successful than their 3300 and 3600 counterparts even though both had 16 cylinder prime movers too.

EL U33C #3311 - Erie Lackawanna Description: Built by GE and delivered to the EL in August, 1969, this clean looking unit heads off into the yard at Saddle Brook, NJ.

All of the Athearn '70s U-boats, U28-U30-U33, feature wider than prototype hoods. This was done to accomidate the drive motors used at the time. The boats were issued with metal trucks, though plastic truck sideframes and new drives would be standard by the 1980s. The U33-C shell includes a lower headlight mounted on the top of the nose.

To make room for the new C30-7A's in the early 1980's, Conrail renumbered the surviving U33C's into series 6845-6883, which had originally been occupied by RSD12's. Here CR 6845 (former CR 6540) sits in the scrap line at Selkirk. Parts have already been salvaged from the unit.

ALCO Models releases its HO-scale brass U33C in early 1971. The model retailed for $56 and featured a 7-pole motor. General Electric built 375 examples of its 6-axle U33-C diesel between 1968 and 1975.
