Today we have 5 new parts!
First up, two new versions of the Leslie Supertyfon S-5T. Both versions of this horn have all the bells facing forward. The first version, the S-5T is an older one, with tab back power chambers. This specific version is aimed at the Western Maryland modelers (we got some more horns coming for you guys’ next week!) but certainly used by others as well. The second version is the RS-5T, with the post 1979 spike back power chambers. I do not know who used these stateside, but this horn was common down in Australia. Both of these come two per package.

Next is another axle generator, this one a variation on the GE MM24. This generator is mounted on the 8-bolt, angled oil bath style journal cover. These were common on lots of late era RS’s including RSD12’s, RS27’s and others, as well as some early Centuries and GE U boats. These were used for the wheel slip system and typically had a cable drive speedometer on the other side of the locomotive (we have several of those too!). Includes 4 per pack with two wire options.

Common to almost every locomotive is the basic ground/step light. A simple sheet metal housing with a mounting flange. Our set includes 16 lights: 8 with a mounting stem, and 8 flush mounts. The stem version has a hole in the side of the housing for the wires, and the flush version has a hole in the center.

Last part – I am happy to finally introduce our new line of scale coupler buffer plates! These have been in the works for some time. This first version is for the EMD GP9/SW1200. This is a wider, fabricated style. This is just the detail for the pilot – the stock coupler boxes are still used, just trimmed down. This coupler plate is wide enough that a standard KD shank will fit through it easily. Note, these do require some scratch building work in order to fill the pilot gaps left by the stock parts. Each pack includes 1 pair.

We have several of these coming, including the Alco Century, Alco RS, Alco S, GP7, 1st Gen Switcher, Late 1st Gen EMD and Dash 2 EMD.
More stuff to come this weekend, including our first Leslie “U” horns!

Two new horns!
This week we have a unique, older horn, the Leslie Supertyfon S-3J-R. The “J” horn was part of Leslie’s initial offering of 3 chime horns in 1952. The horn uses the original high manifold, which was very narrow, as well as having the center bell raised up higher. This horn used bells #277, #330 and #440, with the larger #277 being two-piece construction, none of which have the large Leslie name blocks on the sides. Tab back power chambers are used.
We are offering this in two common versions for now – the Great Northern style, which has the #330 bell reversed on the left left. Some of these lasted into early Burlington Northern, specifically on the F units. The second version is a more “traditional” reversal, with the #440 reversed in the center. PRR (well into PC) was a large user of these, but they also showed up on LV, B&M, Rutland and some others.

PRR, Others – https://gothamrailmarine.com/product/leslie-supertyfon-s-3j-r-version-2-prr-others/
This is a unique horn and very good sounding horn, not to mention a very rare one now. These will start shipping later this week. We will have a few more announcements later this week for the Spring Modelers Meet!

3 New Horns!
First up, one of the most highly requested and most recognized horns ever made – The Nathan Airchime M5R24. This version has scallop base bells and manifold, making it a post-1952 horn. This is the catalog arrangement, with the #2 bell reversed on the bottom right, and the #4 bell reversed on the upper left. This horn was common on a ton of passenger engines, as well as really everything else, right down to NW2’s on Western Pacific. Like all M horns, they fell out of favor and an M5 is all but a museum piece today. If there is enough interest, I will also offer this in early round base bells, but I doubt most modelers would care.

Another M horn – this time for our Canadian friends, the M3HR4. While a basic M3 uses bell/heads #1, #2 & #3, the M3H uses bells #2, # 3 & #4 with #1, #2 & #4 heads in order to blow the Canadian mandated D Minor chord. This horn features the common Canadian reversal, with the #4 bell reversed on the left. This is also scallop based, dating it to post-1952.

Last is the Nathan/Nathan Airchime K5HR24/K5HAR24. The 5 chime “high” manifold was one of the original K parts, however this horn uses the later, non-adjustable caps, dating it to post 1969. This horn will double as both the Canadian K5H which uses bells #1, #2, #3, #4 & #5 (used one a number of US built GE’s into the early 1990’s as well), and the US version, the K5HA with bells #1, #2, #3A, #4A & #5. This horn has the 2-bell reversed on the top right, and the 4-bell reversed on the lower left.

These horns will begin shipping Monday the 13th.
Before anyone asks, yes, all of the above will be offered in all bell forward configurations down the road.

3 new horns! Well, technically 5…
This release is aimed at Chessie and CSX modelers.
First up is a new version of the Leslie RS-5T-RR (I am calling this one Version #3 for the catalog). This version is a CSX specific one introduced in the early 1990’s, in which the right two bells (31 and #44) bells are reversed mimicking the “R24” reversal used on the K5LA’s.
Next up are two Chessie horns: the high manifold S-3L-R and low manifold SL-3L-R. All 4 versions of this horn use the same basic setup, with the 31 bell reversed in the center however with the 25 on either side. We are offering this batch of horns in two packs: The S-3L-R with one 25 bell left, and one right, and the same with the SL-3L-R, one 25 bell left, and one right. If there is enough interest in these, I will split them up into individual packs.
These will begin shipping early next week!

Custom Horn Program!
We are finally announcing our next custom parts program – this time for horns! Do you have some crazy bell arrangement or mashup of parts you want to replicate in scale? Well, now you can! For a small setup fee, we can put together the horn of your dreams. We have an extensive catalog of parts (see below), with more on the way. There are a few things to note with this program –
– Not everything can be done, due to print limitations, etc.
– These will be handled between our regular workload, so the lead time will be a little longer (the horns have a much longer, non-standard post processing time as it is). You will not be asked to pay until your parts are ready to ship.
– We have several “common” horns already in our queue that will be released throughout the future. This program is reserved for one off/custom horn for road number specific/freelancers: IE, things that are realistically not worth adding to our catalog.
Now – Costs. The horn line is our most labor-intensive part at GR&M, so we are going to be charging an $8.00 setup fee in addition to the part costs: single chime horns are $6.00, two chimes are $8.00, and 3+ are $10.00 per two pack. If you require more, then we will work on a larger bulk rate.
Please EMAIL us with what you’re looking to do, and we will see what we can do!
This program is for 1/87th Scale only right now.
