It may have been economical at one time, but it's not economical anymore. They've taken baby steps to get past that mentality by once again adding six-axle locomotives to the roster (I applaud them for that, having advocated for it for several years), but the average age of the fleet is getting older rather than younger, and that's starting to catch up with them.
Fleet age is a growing problem going forward. Though reliability is an issue I don't think its the reason to go newer. It could be fixed with a capitol rebuild program, like the 2 or 3 that have made the Clipper over the last 5 years but result in a handful of units done before cessation, except carried over the whole fleet. The 40 series package has so many advantages. While largely gone from mainline railroading, all major roads still roster the SD40/-2/-3 in sizeable numbers NS is even buying them on the used market and they are still the first option for any leasing company. Parts are plentiful. The GP/SD40 line has a long future ahead. Pan Am is nicely positioned in that many of its 40's (all the 300's, and some of the 600's) can be overhauled, rebuilt and upgraded without having to worry about current EPA regulations, at least as I understand the tier system. They can strip them all down to the frame and rebuild, and have a like new unit for thousands, rather than millions.
I think the argument for updating and reducing fleet age shows in other ways besides reliability, namely efficiency and power.
Either a C40 or SD60 is going to replace SD40's at a 3:4. An average road train can have 1 fewer unit and get over the road.
They are more efficient, built on the post 70's energy crisis platform, rather than the 60's muscle platform, a they put out more power and drink less...
It will happen, its only a matter of time and cash for something newer to show up and rule the roost on the road.
