Flatcars Prototype: Detailing the Underside

After busying myself for a while with the bogies and couplers, it’s time to start detailing the flatcar. Though they are not that striking at first glance, the details will significantly add up to the overall picture. And since they are the most visible parts, I’m starting with the trusses or more specifically the queenposts.

Flatcar Prototype: Bogie-Mounted Couplers

Based on my lessons learned during the last operation session, I’ve already started to mount couplers to the bogies. The result works very well, however I’m not quite happy with the looks: too clumsy, too heavy. So I’m trying a more delicate approach for the second coupler.

Flatcars Prototype: Lessons Learned from the Operation Session

Our Summer Operation Session was a lot of fun, but most of all it was informative. I learned three very important lessons concerning my flatcars:

  1. Frame-mounted couplers need large radii
  2. Bogies need clearance for operational reliability
  3. Bogie-mounted couplers increase reliabilty

Flatcars Prototype: Floor and Trusses

After preparing the frame and floor boards, construction can continue with the underframe. The main components are the body bolsters, needle beams and trusses. Unfortunately, I don’t have got a complete set of diagrams, so I had to guesstimate concerning the longitudinal and cross trusses. However, it’s not rocket science.

Flatcars Prototype: Materials and Frame

Based on my experiences from the flatcar experiments I’ve decided to construct a prototype for 26′ flatcars. The model is going to be built from red cedar and purchased Piko bogies.

Flatcars: Experiments

Before I start the actual construction of my planned flatcars, I’d like to know first which limits the tracks will pose on them. I’ve only ever known classic model waggons, which have their couplers on beams attached to the bogies. This design ensures high operational reliability because the couplers can follow even the tightest curve radii. However, it’s not a pretty sight.

So I’d like to build a few test waggons in order to learn how the couplers perform when attached to the waggon’s body.

New Construction Reports: Flatcars

For our next operation session I’d like to contribute a few waggons of my own. In that way I will stick to my intentions, that is to focus on a complete train for the time being.

One better starts small. That’s why I’ve picked the construction of freight waggons, precisely: flatcars. The reasons are natural: most US freight waggons based on flatcars or were closely related to them. Furthermore they make the easiest waggons to model, apart from disconnects and skeletons.

Timber Cargo for Bulkhead

In preparation for the next driving session at a friend’s of mine, I focused on Bulkhead #101. (By default, which other waggons do I possess right now?)

The little darling is supposed to serve as a coupling adapter (knuckle coupling at the front, LGB’s “bottle opener” at the rear). So that it can excel in the task, the waggon needs some additional weight, which I provided by means of a timber load. And in order to keep the latter in place, some fastening had to be added.
