Does MTH have a Bettendorf caboose truck with leaf springs for three rail?

Does MTH have a Bettendorf caboose truck with leaf springs for three rail?

Looking to adapt the MTH 20-89015 caboose truck for three rail use on wide vision caboose models. Has anyone found a way to do this?

As far as I know MTH does not have a three rail version of this truck with extended couplers.

The 2 rail MTH trucks are shown.

MTH 30-77216 has them I believe. Can't post image right now. Just got it posted.

The 30-77216, based on the MTH website product locator, does not have these trucks.

It has the "I-beam" trucks (as I incorrectly call them), which many people confuse

with "arch-bar" trucks.

I am almost certain that MTH would not tool up for a strictly 2-rail truck. A 3-rail version

must exist. I'd like some too. 

Far from an expert, isn't that the same truck?

MTH does need a much better parts display, Midge is a trooper without us having P/N's.

No, the "I-beam" truck (I wish that I could recall the actual name!) does resemble an

old-fashioned arch-bar in general shape, but it is a modern, cast-steel truck, with 1-piece side frames.

The arch-bar began in the 19th century and is bolted and riveted together from many

pieces of flat steel and iron stock. It was outlawed in interchange service before 

WWII, as it was far less durable and safe than the later cast trucks (of all kinds). It 

also required more maintenance. It lasted in work-train/MOW service for a while

longer.

I believe the common MTH caboose truck is called a T-section Bettendorf truck. It was one of the earliest trucks with cast one-piece sideframes and was used from around the turn of the century into the 1920's. It is anachronistic for any steel caboose. Here's a picture of the MTH truck.

Weaver HAD (past tense) archbar leaf spring caboose trucks #P752.    I am out of them....they are no longer available, per Weaver.  I would love to find a source for

other caboose trucks...even Bettendorfs.  I don't know if Weaver once made leaf

spring Bettendorfs.  I have occasionally found "different" trucks made by Walthers,

whose 2-rail or 3-rail wheelsets interchange, but they are hard to find.

They don't have a 3 rail version.  I went through this years ago.  But, their 2 rail version has a 3 rail coupler.  I purchased the 2 rail version and replaced the wheels from the trucks I took off.  The pickup is the only issue.  I just answered the same question recently.

MTH makes a decent 3 rail representation of a Santa Fe steel caboose, except for the trucks.  The produce a proper truck in 2 rail.  Why not 3 rail?  It doesn't make sense.
