New Coil-Elliptic truck


Brian Leppert <b.leppert@...>
 

Available now from Tahoe Model Works is the new HO Coil-Elliptic 50-ton freight car truck.

This is the Double Truss version, with a centered leaf spring with coil springs on both sides. The prototype trucks either had a spring plank or were Self Aligning Spring Plankless. I've done the truck with a spring plank.

The railroads that I know of using this kind of truck on some equipment during our period include BAR, C&O, CGW, DT&I, Erie, LNE, N&W, VGN and WM. Some AC&F tank cars built in 1937 also had them.

Anyone wishing a flyer, please contact me OFF-LIST at

Anyone have a roster of cars using this truck? I was
only aware of some DT&I and CGW cars...

Oops, sorry all. Meant to send that off-line.

Tim,



N&W used these trucks on the B-1, B-2 and B-3 boxcars; there may have been other classes, but I'm not sure right now.  Also, I think VGN used them on the 50' "round roof" boxcars (similar to N&W B-3 and PRR ???).

I'm trying to gather up my notes into a roster, but, after recent discussion on Morning Sun accuracy, it'll take a little longer.

Some or all 1932 ARA box cars owned by BAR, C&O, CGW, Erie, and WM had this truck. Also, round roof box and auto cars owned by N&W, Virginian, DT&I and Western Maryland. Lehigh & New England loved it.

And others...

Oops, Western Maryland didn't have round roof box cars. I can add that their 50701-50800 series 52' gons, blt. 1937 with steel floors, had this truck--I think. Sunshine does the kit.

Careful, we'll start calling you Santa Claus... Making his list and checking it twice...

You got a workshop staffed by elves turning out those trucks? :-D

It has been brought to my attention that I posted a pricing error yesterday on the TMWs wheelset-less sideframe pairs. I incorrectly gave the price as $1.75/pair. The correct price is $3.00/pair. The usual industry apologies apply. Thanks,

Hi Andy,

Thanks for the copy of Brian's new Coil-Elliptic truck flyer. Since there is a little confusion over pricing and the listing as Code 88 wheelsets, can you clarify if they are available in semi-scale Proto-88 wheelsets.

Earlier, you had said that Brian had stopped using Intermountain Proto-88 wheelsets due to their non-conformance to his standards and was going to use Reboxx Proto-88 wheelsets. Are these now available in proto-88 semi-scale reboxx wheelsets or do you recommend just buying the side frames?

Best regards,

Tom Olsen

Tom, I am guilty as many others in semantics, particularly when it comes to RR terminology, but this is quibbling. Semi-scale wheelsets are .088 " wide, so many times they are refered to "code" 88. There are no other wheelsets available in the commercial market with a confusingly similar notation, so do not worry about the choice of words.  Do not confuse code 88 with Proto 87, for they are not the same.

I recommend purchasing TMW trucks with the wheelsets you intend to use.

That is simply not true. "Code 88" is the designation specified in NMRA RP-25 for a wheel made to specific profile, and NWSL, among others, makes wheels that are indeed that profile. The IM and Reboxx are not, and therefore are not Code 88 wheels.

NMRA RP-25 specifies ONE profile that is made proportionally larger or smaller to suite the scale. Since the same size profile could conceivably be used for more that one scale, the NMRA used an arbitrary designator, CODE nnn, nnn being the width of the wheel, similar to how they designated rail, which is also multi-scale. However, the NMRA never intended wheels of different "CODE" sizes to operate on the same track. That is an adaptation that modeles made when they noticed that it happens to work, kind of.

Now, as it turns out, there are a lot of reasons why the IM and Reboxx .088' wide wheels with flange dimensions that match the NMRA Code 110 wheels are more desirable. Since the flanges are exactly the same as the flanges on the wide wheels, flangeways can be filled to allow the flanges to be supported by the bottom of the flangeway, thereby eliminating the "bobble" when crossing frogs. But, there needs to be a different designation of the Reboxx semi-scale wheels, so they won't be confused with real, correctly proportioned NMRA CODE 88 wheels, which for our purposes are actually less desirable.
