A loco (built after set 112-2) pulled 20 two-axle “oldschool” cars.

Does the fixed two-axle type freight car offer more resistance around curves
compared to modern swiveling trucks like I imagine it would? Or would it
depend on the length of the car itself compared to the curve radius?

Good question - depending on my former tests, I would guess, that short 4-wheel
waggons (like the lightweight barrel waggon from set 2126) with not more than 6
studs distance from wheel block to wheel block offer the lower running
resistance. Any car with bogies has the doubled amount of wheel sets and this
ends in higher running resistance on straights.
So if you want to make up the train with most cars, use short 4 wheel ones.
(disadvantage in curves: the wheels biting the curve / advantage: only 2 wheel
sets per 20 studs total length).
If you want to have the longest possible train (in absolute length), try to use
cars like the Set 4543 with low weight and
28-studs baseplate. (advantage is the wheels not biting the curve / disadvantage
on straights: 4 wheel sets per 32 studs total length => still more wheels per
length).
Both types have their benefits, one on straights (and this is the longer part of
the train), one in curved section (this is the most critical area, where magnets
might tear apart).
Another question is: if you have a mixed train - where should the bogie cars be
placed? In the front or in the rear?
In my tests the rear seemed to show slight advantages, but I cannot explain why.
Are there rules from real life trains, how to mix two different kind of waggons?
Leg Godt!
