Don Glenwood's circa 1970 reprint of "Recent Locomotives (1886)" is apparently not online, but available from used booksellers. This has six 4-4-0 drawings from the 1880 edition, and seven more from t

The latter PSC HOn3 trucks have a similar problem with wheel sets falling out, particularly those with Acetyl (aka Delren) bolsters. A useful option is to glue one side frame to the bolster, using ACC

Drew No C&S boxcar doors, but I do have a few extra D&RGW 3000 series boxcar side doors. These are miss-shot door sprues from the Grandt 5001 boxcar hardware set, but the side doors are filled. Its th

Ed The D&RGW drawing of 2/27/1926 for #32-81 is reproduced as figure 3-11 in Sloan's "A Century + Ten...". This is the same drawing that was once available from John Maxwell as a 1"=12" scale blueline

Rob and Brian Grandt Line did this car in Hon3. Also the steel underframe boxcar and refrigerator, and the 4-wheel caboose. I do not know if they are back in production yet, but the kits should still

Dusty et.al. I believe that Grandt HOn3 trucks were initially supplied with a #0 wood screw. A #0-80 should work well. With these small taps, when tapping metal I find it useful to give the tap a half

Following up on my previous comments, I attach a copy of the Railway Review article on the D&RGW K-28s. For those not familiar with the Steam Era's railroad technical publications, most of the publish

Mick The ALCo K-28 drawing puts the boiler CL height at 78", as does the USATC drawing for when they were on the WP&Y. ALCo claims the outside diameter first course is 63.5", USATC gives this as the i

Jim & Earl Regarding folio and similar measurements: The D&RGW locomotive diagrams issued in the 1950's, and formerly available from the Maxwell Collection, do indeed show boiler barrel "OD"s. This is

Regarding the five C-25 equivalent engines: These were not exact copies of CR #103, and that engine was twice severely modified by the D&RG, first with a an extended cab and later with a near standard

Doug Kadee 714 scissors couplers (and the brown version 715? ) are the defacto standard for HOn3. They are somewhat oversize for the full size MCB couplers used on the Colorado NG roads. Since the cen

Tony Your Rotary listing is short by 2 or 3 dozen. There appear to have been 17 more steam Rotaries built in Japan for local use, and a similar number built in Europe: I believe that the 42" gauge Jap
