Oh, a cab car. Oh, the PaTrain had one of them. I have some old Polaroids around here somewhere that I shot of the PaTrain. Ok, I am withcha now.
In this photo there is a shiny silver bead between the 2 purple sections this is abs “weld” instead of using bondo to see how the 3d pen worked as a filler.

In this photo you can see a green stripe between the grey and purple sections, this is ABS plastic “welding” using a 3d printing pen instead of using bondo or other joint filler…

Progress, need to print the bogies next
Will your cab car end (Bombardier style car) have two end windows or one?
Just curious, as the GO Transit photo shows two windows. Most Metrolink cab cars I’ve seen only have one:

I wonder what the window configuration is for other commuter rail systems?
I’m going with the 2 window version

Yeah, looking over photos on the internet the 2 window version is the way more popular version.
Wouldn’t be that hard to make both though literally would take less then a minute to change the 2 window version to 1 and send to a printer…
Yea, then you could take the 2 window version and fill in one window if you need to. Besides, it takes less plastic to print it that way.
Mark, is that car is strong enough as is? I mean, do you need to add a supporting frame to it so it holds together?
I was planning for a piece of metal to insert into the bottom the length of the car to provide lower center of gravity and to be able to screw the pieces into it so that long trains could be achieved…
Wasn’t smart enough to think of that before I glued the prototype together, but this one is a shelf queen, well actually a flatcar queen and will not be used for passenger service so no worries with this one.
The next one will have weights added…
I would think something like an inch wide piece of aluminum, bent along under the car would work… Would give a solid attachment for trucks and couplers, and be easy to bend into shape.
Cab end is on the printer tonight, will have pictures of it tomorrow

Well I was wrong, it took 2 and a half minutes to make the window change, boy was I off on that estimate. The 2 window version came out spectacularly will post a picture later, going to try to print the 1 window version later today/tonight

Yeah, dreadful and way below par. You should compare that to the time it takes LS mfgs to correct mistakes, never mind simply changes.
Well in their defense this isn’t a “mistake” it’s another version that would take them months to produce 
Cab end, double windows
Mark, no it wouldn’t take months. They would announce it months after the original version was produced, then push back the expected delivery a few times. Then 2 to 3 years after the announcement of the new version, they would show a test shot, but say its going to be delayed again because the shot has some “issues” that need to be corrected. Then another push back on the expected delivery. Then the whole project just simply fades away, never to be seen again.

Sheesh and here I thought I was cynical enough, but you added a whole new layer. 
Mark , the blue coloured end portion has a marked “ply” look about it . The effect is more pronounced than on the previous items you have shown
Is that because it is a test shot using different plastic or whatever controls the final finish ?
Don’t take it as a criticism , I just would like to know before committing to taking further interest .
Mike
low resoloution test print, with no sanding or alterations, it’s a raw photo off the printer…
Fine Mark , thanks . Not having used the machine makes for odd questions .
I think you have a convert . Me .
Mike
The printers don’t quite like building angles upwards, the layers tend to smear more, that I think is what your seeing, on flat surfaces where the layers are built on top of each other there is minimal issues

even at low resoloution this is easy to sand out and smooth up ( the inside has not been cleaned from some of the supports and you can see some interior flash.)
