Good evening all:
I could use some prototype information on a unit for a potential modeling project,especially from any former GE/Erie folks working in the late-1970s to mid-1980s. (NOTE: I have done extensive research on this unit far and wide, with limited results).
Most (if not all) Conrail E44s were upgraded to the model E44a, which, among other things, ditched the ignitrons in favor of silicon rectifiers. While Conrail was still vacillating about continued electric operations, GE tried to help them along by taking a single E44a, #4453, and upgrading it completely with new electrical systems and electronics. It was a one-of-a-kind unit, rated at 6000hp that tested on the NEC for a bit. From Wikipedia:
"Conrail subsequently swapped out the ignitrons in all of the remaining units for silicon diodes in the late 1970s and early 1980s, in-house and without any horsepower upgrades. In 1980, GE took E44a 4453 in hand for rebuilding with upgraded electronics and up-rating to 6,000 horsepower. Made redundant by Conrail's discontinuance of electrified freight operations, the rebuilt 4453 was briefly tested on the Northeast Corridor in 1984 by GE, who then scrapped the unit several years later after salvaging the newer components."
I have done extensive research via all avenues I could access to find out more about this unit. Some pictures do exist, and one can easily spot the differences from regular E44(a)s. There is an extra channel, vents and related details along both sides, considerably more above-cab roof electrical hardware, a newer radio antenna on the left side above the horn, and the elimination of the aft pantograph. Aesthetically, the cab number font is larger and slightly 'un-Conrail', and the number boards use a font somewhat reminiscent to the early Amtrak AEM7 number boards.
I am looking to replicate some of the details of this unit on one of my MTH Conrail PS3 E44s. In particular, I am very interested in the roof electrical hardware and upgrades. Does anyone have any other pictures or slides of this unit, documentation or any other information on this unit? I would be especially interested in data from someone who many have worked at GE/Erie during this time.
Thank you in advance for any information.
