About the Brunel

The Brunel vertical boiler engine is now Mark III of our most popular steam locomotives. It is the first geared engine to be manufactured by Mamod and this, combined with a slide valve piston and cylinder arrangement, makes it one of the most powerful locomotives Mamod has to offer. It has internally framed wheels which can be adjusted to suit either a 1 gauge or 0 gauge track, allowing for flexibility for any steam enthusiast.

Add flair to your Brunel with this boiler cladding kit. The cladding kit must be fitted at home by you. reach out to the team at Mamod for more information.

History of the vertical boiler

The design of this great locomotive was based on the original De Winton type engine which had a vertical boiler and a narrow gauge. They were manufactured during the late 18th century and could be commonly found working the Welsh slate mines.

    I first saw the Brunel at the Summer Steam-up in Sacramento California and was impressed with the running characteristics and the price is reasonable for an entry level steamer. I have been getting 35+ minute runs on fairly level track, it seems to handle grades without issue and I like geared locomotives.
    I would be giving this unit 5 stars except for the pop rivet construction and the lack of a condensate pipe to keep water/oil from blowing all over. I solved this problem by making a condensate tank to collect it all.
    In summary. It is a fun entry level for those who may want to test the steam side of the hobby without breaking the bank.
