The ALP-45DP has exceptionally high axle loadings and, to the best of my knowledge, is the most expensive locomotive ever built. It should have been clear from the beginning that such an exceptionally heavy locomotive would be hard on the track structure. In the end, the real choice is between AMT upgrading CN's track, or reducing the weight and axle loadings of the world's most expensive locomotives, something that is hardly feasible. So the real solution is to pay the price in terms of track upgrades, maintenance and more frequent track inspections.AMTFan1 wrote:
To me, that seems only the consequences of having prioritized only freight trains and not passenger trains since CN is a private, freight train company, so their tracks are only good for freight trains and old less fuel efficient locomotives, and not brand new, high-tech trains...
You can listen to this report, and read the news report about this, even if it's in French, at the following link: http://tvanouvelles.ca/lcn/infos/region ... 70256.html
Here's a google translation of the article:

It would be interesting to compare CN's track structure in the Montreal area(weight and age of rail, tie material, spacing and ballast) with the track structure that NJT is employing, both on and off the NE Corridor. At very least, there are two commuter rail agencies using the same locomotive, and I'm sure that they are comparing notes.
