SD40T-2 to SD40-2
Posted by RailEagle on Friday, January 18, 2019 9:34 PM

Saw one owned by Cemex in Victorville.

Two broad questions:

Why?

How?

Why they did it simple easier maintenance and lower maintenance costs. The T-2 has the fans lower towards the walkway and blows the air upwards thru the radiator cores. The standard models pull the air thru the cores and the fans are in the open at the top for ease of access.

How they did it simply cut the radiator section off replaced it with a 40 series radiator section replumbed the water lines rewire as required fill in the holes on the walkway prime and paint.

The unit could have been in an accident and suffered rear end damage. 

Or perhaps the old radiator and cooling system suffered some sort of mechanical failure, and it was cheaper to replace the whole section with a standard radiator and long hood end.

Google is our friend.  Here is SP 8507 in its later days outside the Sacramento shops.  Appears to have been used as a parts source.  Note that the radiators are missing:

Thanks!

PS: As an SPSF modeler SP 6600 (Next slide over) is very interesting...

To add a little extra to the story, the January 1995 issue of Trains said she had been wrecked on SP, which precipitated her being retired and sold to Helm for rebuild to SD40-2 specifications at such a young age. After being used as a lease locomotive, it was sold to SWPC after they had wrecked their GP40/slug set.

I wonder if her and the SDP35 are still employed today?

She is. I just photographed her in service Saturday moving a few cement hoppers to the Cemex plant. I do not know about the SDP35.

Edit: Ignore this bump, I thought the topic said SD40T-2's and SD40-2's as I looked back for an appropriate thread to post a question in.

I had forgotten what it was actually about, so my SD40-2 question was well off the original topic.
