On30 Tunnel Portals

Are you in need of a tunnel portal or portals for your On30 layout? If so there are several options available -- either commercially available R-T-U (ready to use) or you can scratchbuild to meet your needs.

Commercially Available Tunnel Portals for On30 Layouts

Here are some commercially available On30 and O scale tunnel portals:

We have included some S Scale tunnel portals in the links above as some On30 modelers have decided on the use of S Scale tunnel portals for On30 layouts. Also please note that most if not all of the R-T-U tunnel portals still require stain/paint/weathering, and some are kits.

Scratchbuilding On30 Tunnel Portals

If you prefer to scratchbuild tunnel portal(s) you might consider these references:

There are also numerous magazine articles providing reference and how-to information for various types of tunnel portals. A few of them are listed below. For a more complete list visit the Trains.com Magazine Index - you will need a (free) account on Trains.com to use the index.

  • Select list of magazine references to be supplied after research is completed.

Model Power Plymouth MDT Locomotive - On30 Critter, Donor chassis, or both??

Many may already be aware of this but for for those who are not -- Model Power offers an HO Plymouth MDT locomotive. It's significantly oversized for HO scale -- both the shell and the wheels. In fact some in the On30 crowd use it right out of the box as small diesel or critter on their layout. It seems this locomotive has been around for a long time, but the most recent release from Model Power is a smooth running locomotive with great electronics built right in. I've purchased a few of these and have been very pleased.

It is also a great donor chassis for an On30 critter and some like Tim Moat of Coyote Flats Depot offer critter kits built on top of this chassis (kits available on eBay). If you're looking for a chassis for a critter that won't break the bank, this may be the solution for you.

On top of all the positives, right now (May 2018) Trainworld is offering these on sale at the unbelievable price of USD $44.99 for the locomotive with what we will call "Do It All" electronics built right in -- it runs on standard DC, it runs on NMRA DCC, has built-in sound, and it has wireless control and controller right in the box or just $19.99 for the standard DC version. The "Do It All" edition locomotive has MRC's very capable DCC/DC dual mode decoder with sound and also integrates its Loco Genie™ right in the locomotive (on-board electronics) and in the box (Loco Genie controller).

If one of these scenarios fits your needs/wants for your On30 layout, you might want to visit Trainworld's web site and pick up one or two...

N.B. I have no financial relationship with Trainworld except as a satisfied customer.

Bachmann Spectrum On30 14-Ton Two-Truck Stearns-Heisler


The Stearns-Heisler continues Bachmann's collection of On30 geared steam locomotives along with their On30 Shay and On30 Climax. This 14-ton two-truck engine was an early Heisler, manufactured from the late 1890s.

The Heisler locomotive was the last variant of the three major types of geared steam locomotive. Its designer and manufacturers claimed it was the fastest of the three but retained the low-speed hauling capability. As such it was used in mining and logging/lumbering industries as well as other places which required heavy hauling. From a 1923 Heisler marketing catalog:

"Why you can haul at least 30% more per ton of locomotive with the modern Heisler"

Bachmann has delivered a DCC-equipped model with the fine detailing expected in the Spectrum® line, along with 16-bit Tsunami® plug-and-play sound capability. (Separate-sale Bachmann Item No. 44953, Stearns-Heisler Sound Module, required for sound on board performance)
Features include:

  • DCC-equipped for speed, direction and lighting control
  • Sound ready with factory-installed speaker
  • Dual-mode NMRA-compliant decoder
  • Die-cast construction
  • Coreless motor
  • All-gear drive
  • Enclosed gearbox
  • Heavy-duty universals and driveshafts
  • Prototypically powered trucks and gearboxes
  • Constant soft white LED lighting
  • Blackened brass handrails and piping
  • E-Z Mate® Mark II couplers
  • Choice of three stacks and optional oil bunker included
  • Contoured wheel spokes per prototype
  • Plug-and-play sound-ready (Tsunami® sound module available separately)

Heisler Locomotives: Books for further reading 

Heisler Locomotive Works. Heisler Geared Locomotives Catalog. Erie, Penna.: Heisler Locomotive Works, 1923, 38 pages.
About this book from BarnesandNoble.com: In 1892 Charles Heisler received a patent for a new kind of geared locomotive. Equipped with twin canted cylinders, the engine utilized a drive shaft to power outboard axles and connecting rods to power the inboard axles. As a result of this 'vee-twin' arrangement, the Heisler was one of the fastest geared steam locomotives, providing more power with lower operating costs. Over 600 Heislers were produced from the 1890's until 1941, when the Heisler Locomotive Works closed its doors. This reproduction of the company's illustrated catalog dates from the 1920's. It shows the full line of Heisler products and presents a compelling argument for their use.

Kline, B.F.G., Jr. The Heisler Locomotive, 1891-1941. Kline, 1982, 199 pages.
About this book from BookFinder.com: Fascinating and handsomely done authoritative history of the Heisler geared locomotive. Chapters include a biography of Charles L. Heisler, a description of the Stearns Manufacturing Co., the Heisler Locomotive Works, the Whitney Engineering Co., the origins, development and refinement of the Heisler, the purpose, distribution and performance of the Heisler, competitors of the Heisler, the construction of a Heisler, Heisler's last years, detailed scale drawings, builder lists, and an owner list. Illustrated throughout with black and white photos. With bibliography and index. Some copies of the book contain an Addenda and Errata Sheet with list of existing Heislers as of November, 1982.

NMRA On30 Clearance Gauge plus more!

If you're getting started in On30 model railroading, one of the key tools to have on your workbench is a gauge to measure essential items. The National Model Railroad Association (NMRA) On30 gauge will measure these items:

  • Coupler height
  • Track gauge
  • Clearance
  • Flangeways
  • Wheels
  • Points

The NMRA 0n30 Clearance gauge includes a NMRA HO gauge (for track and wheel measurements) nestled inside a On30 clearance gauge.

Get yours today direct from the NMRA's Online store (including NMRA member special pricing) or at your local hobby shop (through Walthers affiliated dealers - Walthers item number 98-9).

Additional Notes:

When determining track clearance you generally should factor in which "narrow gauge" you're modeling in On30. Are you modeling a specific prototype or prototype region? Or are you using commercial models? Or some hybrid? Maine narrow gauge cars have different maximums (esp. width) than for example Colorado narrow gauge or perhaps a specific UK or New Zealand line might. Similarly commercially available models have different car end overhang that will affect the necessary parallel track clearance (e.g., in On30 models the Bachmann passenger cars and the Bachmann Forney rear overhand will definitely impact your parallel track clearance on curved sections of track). So it becomes more important to understand what you're checking clearance for in On30. For example the NMRA's clearance for Old Time/Narrow Gauge is primarily taken from the Colorado Narrow Gauge railroads. More detail can be found in the NMRA Recommended Practice 7.1 on Tangent Track Centers and Clearance Diagrams.

Some modelers use an On3 (aka On36) track clearance gauge. If you have one of these handy, it should work as well for track clearance, although the track gauge is different. If you're interested in purchasing an On3 gauge, they are available from the NMRA Company Store.

Building an On30 GE 23-Ton Box Cab

One of the many excellent articles in the On30 Annual 2018 edition is Robb Thomas' article "Designing a Locomotive Shell to Fit an Existing Mechanism" (pp. 81-85). (If you do not already have this issue of the On30 Annual in your personal library, I highly encourage you to pick up a copy from either your local hobby shop or direct from the White River Productions' Bookstore.)

The premise of the article is to help modelers leverage 3D printing to build items of interest for their model railroad. Mr. Thomas used SketchUp and Shapeways to accomplish this task, and the article illustrates the various steps in the process. If you're interested in using 3D printing for your model train layout, you'll want to read this article.

Also if you're just interested in building a GE 23 ton Box Cab for your railroad (and not doing your own design and 3D printing work), the shell, other parts, and the instructions for building the locomotive are available from Prairie Locomotive Works' Shapeways store. The locomotive is built on top of the Bachmann On30 Closed Street Car mechanism that you provide. If you happen to prefer an electric version of this locomotive, the store also features an alternative Freight Motor version of the shell.
