The E-33 (originally EL-C, then EL-3a, EF-4 and finally E-33 or E33) was an electric hood unit built by GE. They appear as 6-axle, very boxy highnose engines. They can be distinguished from the later E-44 by the roofline. E-33s have a raised section of the long hood, but both ends of the loco are at the same level as the cab roof. Also, the E-33 has a sort of semicircular plate above the nose (you'll see what I mean). Only 11 were built, but they ran on five railroads in their lifetime. All were originally delivered to the Virginian in the mid-50s and designated EL-C. http://www.northeast.railfan.net/images/tr_vgn135.jpg http://railpictures.net/viewphoto.php?id=155357 http://www.davesrailpix.com/vgn/htm/vgn11.htm http://www.davesrailpix.com/vgn/htm/vgn17.htm http://www.davesrailpix.com/vgn/htm/vgn54.htm In 1959, the Virginian was absorbed by the Norfolk & Western. Only one EL-C received a full repaint. http://www.northeast.railfan.net/images/tr_nw235a.jpg http://www.davesrailpix.com/vgn/htm/vgn23.htm In 1962, the N&W shut down their electrification. The story of the EL-Cs doesn't end there. They were sold to the New Haven and re-entered service beginning in 1963, now designated EF-4. http://abpr.railfan.net/abprphoto.cgi?june05/06-25-05/NYNH+H304inOakPointYdBronxNY9_2_68.jpg&redirect=1 Railfan.net ABPR Archive http://www.northeast.railfan.net/images/tr_nh309.jpg http://www.davesrailpix.com/nh/htm/nh068.htm In 1969, when the NH was absorbed into Penn Central, the EF-4s came with it. They were redesignated E-33. http://railpictures.net/viewphoto.php?id=158200 http://www.northeast.railfan.net/images/pc4606.jpg http://pc.smellycat.com/pics/equip/pc4602redd.jpg Then the E-33s went to Conrail, keeping the same designation. They were retired along with all other CR electrics. http://www.northeast.railfan.net/images/cr4608.jpg http://www.northeast.railfan.net/images/tr_cr4610.jpg http://www.rrpicturearchives.net/showPicture.aspx?id=64014 http://crcyc.railfan.net/locos/elec/e33/cr4605er.jpg http://www.davesrailpix.com/prr/htm/prr131.htm Don't trust picture captions! The E-33 and E-44 are often confused. http://crcyc.railfan.net/locos/elec/e33/pc4606ef.jpg Three E-33s and two GG1s. http://pc.smellycat.com/pics/equip/e33-4605.gif Two E-33s with part of an E-44 visible behind them. http://www.rrpicturearchives.net/showPicture.aspx?id=529028 Two E-33s lead two E-44s, showing the difference clearly.
