About how many average size modern freight cars does that work out to? I couldn't find anything from a couple quick searches.

NOTHING to reproach yourself for or about!! You said it as you saw it appear and sound right in front of you. I don't believe that you have any bias but I do feel that you shouldn't feel pressurised in any way whatsoever into appearing to be "climbing down". Why should "ANYBODY" have to go to the trouble of correcting something which should NOT have been so faulty in the first instance??
I have three MTH SD70ACe units on their way across the "pond" to Wales here in the UK and this was due to the fact that you mentioned the difference in weight comparison. Both have some faults but it is totally pointless in having a model which, in comparison, wouldn't pull the skin of a rice-pudding!! A very good review indeed.
Cheers,
