    On30 RR Trucks wheel size -and- dimensions

    I'm working up a kit build of a Rusty Rail On30 freight car and need trucks for it.

    I had attempted to get dimensions for the Bachmann trucks on their website,

    but only got a couple of replies.

    Bachmann's monitor didn't even bother to reply so I bought one set of each and measured

    them myself.

    I'll list the sizes in the next post.

    I was disappointed that Bachmann doesn't offer the dimensions of their products and even more so after getting them and doing some actual measuring.

    I'm hoping this might be useful to some others and if anyone has other On30 brands

    that you would like to measure and contribute to this thread it would be a good reference.

    EDIT: added info 7/3/09



    If anyone has any of these trucks and can supply the missing dimensions, I'll add them into the table.id="maroon">

      This could be a great resource. I have a set of San Juan trucks that I just got that I could measure and add.

      I'll measure them tonight.

        Dave- thanks for this; I can definitely use it. Same goes for the San Juan trucks and their wheelsets ( I don't know why they don't list the specs).

        Please post the measurements! This will be a handy reference.

        It's one of those "when I get around to it" things... now I guess I should go to Caboose Hobbies and pick up a set of the Grandt Line On30 wheels, just so I know....

          Some of the smaller manufacturers do give the dimensions, but I thought it would be nice to have all the On30 sizes in one place.

          When a few more are posted here, I'll combine them into the table I started so you don't have to go through he entire thread.

            San Juan http://www.sanjuancarco.com/p_truckkits.html should have 26" wheels for D&RGW/C&S in On3 and 24" for WSL. Haven't seen any of the On30 wheelsets but I et they are On3 pushed in.

            Foothill Modelworks http://www.foothillmodelworks.com/DetailPt.html for Macleod Western trucks again wiht 24" or 26" wheels depending on the prototype.

            International Hobbies in Auburn CA carries 4' WB Fox trucks and archbars but don't see them on their web site

            all of the above should get you started.

              Dave- here's another to add:

              Grandt Line #3113 set: SR&RL trucks w/ 22" wheels

              -Nice little set of trucks that will work well on small cars (On30 gauge, not 2 ft !!)

                Dashman,

                Thanks. I'll add that to the table when I get the WB and Ht. and Coaltrain is getting the San Juan info too.

                    I have built solid CAD models of the standard Bachmann arch bar freight and the San Juan 21-30 trucks that I use to design my scratchbuilt freight cars, it helps me get the car bolster and coupler heights correct.

                    If anyone wants these files I can send them in several different versions. FYI, I use Autodesk Inventor to model my models with


                    here is the San Juan 201-30 truck I made.

                      How are the Grandt Line trucks in On30 as far as rolling abilities? The HOn30 ones are alway's the free-est rolling trucks. This is a great thread. I didn't realise the 3rd Bachmann option 29903 long wheel base truck existed.

                      For the Maine modellers here a question: I assume the Bachmann 29904 is the best choice for a Maine narrow gauge car?

                      Thanks

                        San Juan has a number of On30 trucks but they don't give any dimensions on their web site.

                        Boulder Valley has a couple also that I will add to the list.

                        Remember, I'm only doing this in On30, NOT 3' or 2' gauge

                            I have a set of Macleod Western trucks with 24"

                            metal weels. They look great and are very free rolling and equalizing, but they make coupling with my Bach. porter very difficult. They are are high, even with whittling down the bolster!
