Current generation EOTs

[geepster775]

Someone needs to model the current generation of EOTs. These are made by DPS Electronics out of Bozeman MT. They are made using a composite material that reduces weight compared to the older Aluminum generation from 50 pounds down to 18 pounds. Because it is made from composites, they can and do come in all kinds of freaky colors, and they noticeably do not have a flat top. I've seen the yellow on UP, red on NS, fluorescent green on FEC, powder blue on CSX. BNSF likely uses the orange color. They hang on the side of the rear coupler, and have a (relatively) small pinhole on the end near the top where the nighttime flash emanates from. All the stalwart equipment developer names of old (Pulse, GE Harris, Wabtec, Progress etc) seem to be caught flat-footed.

You know what I'm going to say here, right?

Yep, these would be a nice addition. I tried getting Erick Cantu to make some when he was doing his EOT's, no luck.
NB&M has been getting some recently, some red, some green. Thankfully. The old heavy gray ones are just tired, old, and junk. Communication past 5k feet of train, in eastern and northern Maine? Good luck!

If there were better photos(front, back, side, etc), AND dimensions!, anything is possible.
A casual look online and I could not find much of that! Otherwise, it really is an EOT to do this.

Yeah, no kidding. I expected to find more... so *fudging* is required.

If you click on the link to the manufacturer in the original post, and then click on either of the two photos, each brings up a series of about 10 photos covering 360 degrees.

The one side equipped with reflective striping is what faces outward behind the train when mounted. The little hole in the top left is where the flasher unit resides.

Images allow a modeller to create an object with the right proportions. At a minimum, at least one measurement, preferably the length of the EOT device would help ensure that the object is built to to the correct 1:1 scale. A modeller could estimate the scale by using known dimensions of other objects in the image at the same depth of field, like the Rail Tie Plate, but that requires fudging that in turn introduces inaccuracies that then requires rework and wasted effort in order to resolve.

Yup. That's what I was trying to say.

Wise.
I am always surprised by your tips.

I have photos, I just need to find where they are...

Guessing:

63 cm tall	24.8 in (2 ft 0.8 in)
14 cm wide	5.5 in
17 cm wide at base	6.7 in
13 cm deep	5.1 in

Found the photos. IMG_20190920_143208.jpg IMG_20190920_143201.jpg IMG_20190920_143154.jpg

Excellent. Thanks for thinking of the modeler.

Pete, I may be able to get measurements of these units as I have a couple in my office.

Pete, check your PM's, turned mine on for a sec to send you a little something from the things I keep in my office.
