Summer Operation Session 2020

The first short train, consisting of bulkhead, test waggon and the new flatcar.

This operation session was scheduled rather spontaneously and spurred me into building a prototype for a flatcar. Accordingly, I was quite expectant concerning the experience I’d gain with the new waggon.

Since we only had a relatively short time for operations and I was preoccupied with test runs, there are only a few pictures. In return, I learned lots of lessons.

Flatcars Prototype: Floor and Trusses

The trusses are complete.

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: Experiments

Bogies by Piko and knuckle couplers by Accucraft.

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.

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.
