I found with conventional that the two powered units did not always move at the same speed causing them to push and pull against each other. Has anyone else observed this?

This characteristic is also true in Lionel's Legacy models. My SD70ACe runs slightly faster than either of the ES44AC locomotives, which also differ a bit from each other when run on straight DC. A 3-unit consist would consistently derail on American Models switches unless the faster SD70ACe was in the lead. Fixing the pivoting pilots into a permanent position for all three locomotives reduced the problem significantly, and running them on Legacy AC eliminates the problem entirely.
