Before anyone spends too much time diagnosing what amounts to an incorrect starter base shape to begin with, has anyone tried mating this T4 F/A with the proper C4 base shape that came with the Mullan addon?

I would've figured these ET44AC's had 6 powered axles, and would thus not have the axle weight distribution equipment present on the C4's. Is that not true?

No, you are thinking correctly. ET44AC's are six axle powered with C-C trucks, while the ET44C4's have the A1A-A1A trucks.

GE's ET44AC was its final production model before the company's transportation division was sold to Wabtec. It remains in production today.

I just followed what little instruction was included with the set. They are nice looking engines. I do not, nor intend to get the Mulan Route. No funds available.

All the BNSF Tier4s are C4s

**PerryPlatypus** · 12-19-2021, 05:13 PM

Doh, I had the wires in my brain crossed with my reply, thinking I was replying to something in the CN ET44AC thread... My apologies

Like Geepster said, 100% of BNSF's ET44's are C4's with the axle weight distribution equipment on the sides of the trucks. So using an ES44AC shape is really not optimal unless the F/A adds that equipment (although I've seen a handful of users add them to trucks via texture only)

Some of these replies address my issue, others do not, they are to do with OR-Specific files.
My issue is to get the Engine Files to be read correctly and that is what I asked for help with. Sorry for being abrupt, but some posts get derailed quite quickly.
Gerry, could you post your Engine file for #3894 please? So I can compare it to mine, just the one would do. I feel that is where something is wrong.
Thank you in advance.

**R. Steele** · 12-21-2021, 04:07 PM

From what you've described my best guess is that something went awry with the shape files. In any case, here's my eng files and a screenshot of what the images section of the shape file looks like.

Here's the "wag" section of the engine file that contains the shape information, if you need to see the rest of the file for some reason, let me know.

Thank you. I will check it against mine and hopefully I can find something. They are nice looking engines.

Have a Merry Christmas and may the New Year bring you and Your Family' more Joy!

**slipperman** · 12-22-2021, 03:39 PM

Hi Don,
Going back to your original post. You reported that TSRE5 CE didn't show the main loco shape.
This might be a silly question, but have you copied the main loco shape files from the SLI Mactier Stock set? The readme specifies that shape file CP_GEVO_9365.s should be copied from folder SLI_CPR_GEVOS together with the Cabview and Sound folders. The shape file is incorrect - it should be CP_ES44AC_9365.s (at least it is in my downloaded pack!).
Also the readme includes the line : ex: CP_GEVO_9365.s ------> BNSF_ET44AC_3857.s
... it should read : ex: CP_ES44AC_9365.s ------> BNSF_ET44C4_3894.s

... and, to match the existing .sd and .eng files, the other locos should be renamed as BNSF_ET44C4_3917.s and BNSF_ET44C4_3952.s respectively, not as shown in the readme.

Cheers,
Ged

**Don6218** · 12-22-2021, 04:08 PM

Yes! I discovered that is were the error was from Gerry's posting of his files. It led me in the right direction and now you have confirmed it.

Thank you very much, your help is very appreciated, especially when my old brain needs a little jolt!
