Re: Merchants Despatch Reefer construction

Tim O'Connor

I think most rolling stock has some amount of camber that can be
seen best when the cars are empty. I recall a few years ago when
Walthers produced some correctly bowed Amtrak passenger cars (there's
something like 3"-4" of camber over the 85' length of the cars) that
modelers thought they were defective! But I imagine it's not easy to
cut molds that reproduce the slight camber for freight cars. Door
tracks, doors, roofs would all be affected!

The bow almost seems exagerated in that photo; there's another builder's photo of a car from the same series on the Wikipedia articlel for MDT which I beleive is also from the Detroit Publishing collection. I've never noticed such a bow before , but if I stare at it there does seem to be one. Side shots of cars from the same lot in service do not exhibit bow; and very old cars exhibit a bow but the other way. My guess is the truss rods may have been a bit overtightened to compensate for settling of the hardware under road and loading conditions. Just a guess. I also suspect some of the bowing is due to the angle of the shot.

Hope everyone is enjoying the holiday weekend. I have copied the link to
a c.1906 photo from Shorpy,

of new Merchants Despatch reefers. All of them look new with a *distinct
hump , floor to roof line*. Is this typical for this type of
construction? The older reefers down the track appear to have flat floor
lines. Thanks.
