Based on the proven Roundhouse Katie chassis and body


Irene is of typical narrow gauge saddle tank locomotive design. Though not a model of any particular engine, she draws inspiration and features from a number of famous builders.
The coal-fired Irene runs without attending coal or water for up to 17-21 minutes (a gas-fired locomotive runs under similar conditions 20-25 minutes). The boiler contains all water for a full run. After a run coal and water is topped up under steam. The advantages of this coal-firing system are explained on the special design features page.
The Goodall valve for topping up the water is hidden under the filler cap on top of the saddle tank. The stainless drop down fire door has a built-in damper function to control the heat of the coal fire and hence the steam pressure. For manual locos see details here.

Keeping the fire going is easy due to a very deep and wide fire-box. The stainless steel ash pan with grate hinges on two pins and can easily be removed. The door of the smoke box is removable (or in case of a conversion the complete smoke box is removable). The cab lay-out is very neat and leaves ample room for a driver. The water gauge and the blower hand wheel are close to scale.

The water level of the boiler is easy to read because of the long reading glass of the water gauge. Just like in a real loco, the red-white or black-white background improves readability of the reading glass even further. A black-white background is fitted as standard.
Your locomotive/kit comes with a Jacksons Superior bottle. Topping up is three times faster with less effort.

Full Remote Control (regulator, reverser, whistle AND damper) can be built in with the Irene RC fittings kit and a RC combo with servos.  Receiver and rechargeables are fully hidden away. The servos do occupy minimal space left from the boiler, keeping the cab uncluttered. The pictures show Irene with full Remote Control.
The boiler dome is prepared for a Regner whistle kit; adding a whistle is very easy.

Building Irene

This is not a "build it in one evening" project. However any average modeler with care and patience can build a coal-fired locomotive to be proud of. All painting is left to the builder, minimal drilling and cutting is necessary. Only simple tools are needed. Read the related FAQs and in case of Slomo these instructions.
The pictured prototype is fitted with optional combination lever & union links, is lined by LightLine and has name & builder plates by Narrow Planet (see FAQ's). The Roundhouse chassis kit is available with optional insulated wheels.

Irene comes as a coal-fired boiler kit and needs additional Roundhouse parts.  You also can use this kit for conversion of a Roundhouse Katie (one extra part needed, read last FAQ). The kit comes complete with boiler certificate and step by step instructions and contains the following parts.
