<DIV>The 24 Norfolk Southern ES44ACs do not have CTE software. The CTE feature
you describe is used on Union Pacific AC4400CWs. In order to reduce the tractive
effort to levels safe for manifest trains, NS pusher crews on ES44ACs are
instructed to cut out axles to match the maximum number of powered axles for
that train.</DIV>

Simmons<BR><BR><BR>Controlled Tractive Effort... reduces the TE curve from
145,000pds to 110,000pds when the unit is below 11mph. Normally used in
DPU operation on manifests on other roads... however, it would make sense for
it to be enabled even when manned, given that these units are max axle load
units (432,000lbs) and have the high-adhesion software set to 36,000/200,000
(36,000lbs max TE per motor, 200,000pds max TE for the unit)<BR><BR>Robb
