Hi,

From the sale notice it seems that these units are being disposed of because they don't have alignment control couplers. There is an interesting accident report on why such couplers are important at http://www.tsb.gc.ca/en/reports/rail/20 ... 2C0050.asp
The report is good reading for those interested in proper train braking technique.
