C-40-4's were built by Pacific Car & Foundry in 1961 for SP #1400-1599. These introduced a lot of new features, as well these had a taller bay than previous (C-30-x) units and exposed rivets on the bay.
Starting in 1973 one caboose from each class C-40-4, C40-5, C-40-6, C-40-7 and C-50-3 was rebuilt and renumbered. Most changes were internal, chemical retention toilets (no more sewer chute), roofwalks and end ladders were deleted and electrical and radio equipment was upgraded. Starting in 1974 thru early 1975, 123 14xx-15xx series were rebuilt becoming the 4000-4129 series class, the 4120-4121 and 4123-27 numbers were not used... As with the loco rebuilding programs, cabooses were given the next number out, so they were not renumbered sequentially with their old numbers.
new features:
- double 'frog-eye' roof mounted marker lights,
- external fuel tank,
- roller bearing trucks,
- as built all orange bays
Details:
- roofwalks and end ladders as built,
- 'funky' smoke-jack as per the Athearn kit,
- partial end-plate on the roof ends,
- square cornered bay windows,
- side and end windows have square corners,
- three windows on the fuel tank side
- two windows the other side,
- notched sill no axle-hung generator,
- delivered with:
- mineral red with orange bays and end walls,
from D. Scott Chatfield: Athearn C-40-4 modeling notes:
I found that the Athearn cab is indeed a very close model to the C-40-4 class, as built, including that funky smokejack. Most (lost?) the square fuel tank (the underhanging box on the right side) by the early '70s. The main mistake is that the markers and antenna should be on opposite sides of the roof from where they are. The Whitehead & Kales C-40-5 and International C-40-6 have a much bigger, tubular fuel tank under the right side bay window, but their markers and antenna are mounted in a mirror image of the C-40-4's (in other words, they match the way the Athearn cab has them). The -5 and -6 are very similar, except the -5 is riveted while the -6 is welded. The later International C-40-7 and early C-50 classes had fewer windows when built and a host of other minor differences.
One significant thing about the C-40-4 class is they were the only cabs delivered with the entire bay window painted orange.
