Am I correct in thinking that there are no external differences between the new AC4400CTE's and the AC4400CW's? [ 22 February 2002, 04:02: Message edited by: BNSF 9965 ]
Yep, for all intents and purposes, they are identical. There are a couple minor changes in carbody doors I noticed in some pics (like this one from TO http://www.trainorders.com/discussion/read.php?f=1&i=121417&t=121414 ),but nothing major. It's only something I'd worry about if I was modeling one. [ 22 February 2002, 05:42: Message edited by: SP 8299 ]
Well I havn't looked real close and counted rivits and all but I havn't noticed any real difference that could be shown in modeling. If you need pics of both versions, I feature several of each on my site. Check it out at Nor-Cal UP AC4400CW Hope this helps.
You still can model it. Details West makes the capacitor box that goes on the walkway behind the inverter cabinet, as well as the shorter hood access doors behind it. The capacitor box is something that appeared on later production AC4400's (some of SP's had em'); offhand I can't remember when exactly, and I'm at work and away from my notes. Installing that on the Athearn model will get you halfway there. The remaining access door (the horizontal door just under the air intake) seen in the TO pic could be added with some sheet styrene.
hey thanks everyone for all your help I really appreciate it. I may need more help before this is done though! [ 23 February 2002, 01:38: Message edited by: BNSF 9965 ]
Does anyone know where I can find a roof shot of the new units? I need to see the antenna arrangement. [ 28 February 2002, 05:41: Message edited by: BNSF 9965 ]
Hello! Does anyone tell me what are the major differences between the new AC4400CTE's and the AC4400CW's? Thank's in advance!
The main difference between the two is in the software inside the locomotive. The CTE stands for Controlled Tractive Effort, which allows the tractive effort of a unit to be electronically reduced when the unit is being used in Distributed Power mode on the rear of a train. This allows for safer operation of a DPU train, as excessive tractive effort can cause problems in train handling including derailments. As noted in the above responses, there is very little visual difference in the two types of units. It is likely that a standard AC4400CW could be turned into a CTE unit with the change of the microprocessor unit.
There is a real small difference between the early and late models of the CTE's. <center> <font size="5"> C4400CCTE Notes </font> </center>
