TT scale trains and models

Quite a number of the units built for SE roads, and the WP and perhaps the C&O did have Blomberg trucks.

However, Al is right, the AAR-B was the standard. 9'4" wb.

Some of the FMs had a 9'6" wb truck.

Okey dokey then. Thanks gents!

I cannot pretend any expertise in gear boxes and the like, but I am wondering if any of the range offered by Markits are of interest? They are some way down in the pdf catalogue on this page.

It's not only about a solution that simply works. It has to be something that makes financial sense for me to do a limited run that others will be able to buy. Thanks for the link though - I'm perusing it.

MTB's trucks have gotten me over the biggest hurdle. I'm happy with the entire chassis - it runs well. Next there are a bunch of details to tweak but they are not a show stopper....just time consuming.

Here is a white train for you.

Summers over Alex your train is covered in snow already LOL ---- but looks and works ok

good stuff.

WE NEED MORE GOLD ...sorry, LOCOMOTIVES!
(As orcs from Warcraft game said)

(but some gold is not too bad idea also... )

That would include SAL, SCL, Family Lines, SBD, and CSX, who all had GE units riding on Blomberg trucks salvaged from traded in locos. The 4" difference it TT scale is about 2 thousandths over 1/32" which is not much. For many years, HO has used the same wheel based trucks to represent both AAR and Blombergs simply by changing the sideframes which just plug in to the truck frame. This should be doable in TT using RP printed sideframes from Shapeways mounted on MTB's 9' trucks as available from CSD. There are also better RP printers out there if you want to make masters for casting them in resin.

Has anyone actually measured the Bromberg sideframes from CSD? In the illustrations I have seen, their sideframes look to be a bit "stretched out", long enough to make me wonder if the wheel base is actually a scale 9'.

I would also think the MTB trucks would be a good solution for the TT GP38 shell that Al and the society have been working on for so long. Just to make things even more confusing, seems to me I've seen some photos of prototype EMD locos riding on AAR trucks rather than the usual Blombergs, also probably the result of trade-ins on new locos, so it can go both ways.

By the way Alex, your U-boat looks great!!! When will you start taking the orders?

Bill, I have a list from like 4 years ago when I first started working on this. When it's ready I'll go through that list first and then offer to others. Likely there will be a single batch with 19 units for sale.
