Hi All,

I thought I would share the latest project I just completed.  I modeled and printed a new cowling for my Dorm Car on my 1957 El Capitan.

Background:

The 1957 El Capitan was a beautiful consist consisting of:

F7 diesel ABBA
Baggage

Baggage-dorm
Step-down-coach
Hi-level Coach

Hi-level Diner
Hi-level Lounge
Hi-level Coach

Here is a video of my consist before I started this project:

I was able to get all Lionel for the consist including the Dorm Car which was only available in a 4 car set.

The prototype Dorm Car had a cowling that basically changed the car roof from normal up to the Hi-Level Car roof line.

Here is what it looked like in its Amtrak livery:

I had decided in the past to make one out of styrene, which worked pretty well which you can see in the video above.

But since I got a 3D printer and got much better at modeling, I decided to create a more prototypical version.

Here is the original:

You can see that the lines are not very good and that it is too high leading into the Hi-Level Step-up Car (which I changed from just upper door to simulate a lower door).

So I modeled the cowling using better measurements (in mm).  I printed the first version forgetting to put the curve on the front.  Then I fixed it and modeled the new version.  Here is a picture of the model as well as the three side by side:

Here is how it looked on the Dorm Car:

Because I didn't feel like trying to model the holes on the bottom to fit over the Car detail, I just used a soldering iron to melt the plastic to create the reliefs (it doesn't look nice, but it works fine):

Next, it was time to figure out how to make it ribbed like the prototype.  I ended up using HO Scale roofing to do this:

Before I received it, I painted the cowling with Silver Leaf model spray paint:

Then I applied the roofing.  It was hard to line the ribs up, but I think it is ok (and when the train is running, you won't notice):

So it is now complete and I put it on the car:

I'm really happy how this turned out. 

I am working on getting the model loaded in the repository so anyone can print it.  Again, the cowling is designed for the Lionel 18" passenger cars due to the roof slope.  I can probably make one with an MTH roof line if it is needed.

Hi Bob,

The side width is 62.6762 mm (kinda to be exact). 

The 3D Repository is found down in the same section as the Buy/Sell links.  The .stl is located in the Parts - Conversions, Upgrades, Unavailable and then in the folder Cowling Santa Fe.

I have the NX Model (.prt) if you want to start with that and not the .stl.  I can PM it to you if you want it.
