Princess Elizabeth No. 6201 – 3-Rail Electric
Product Story
The LMS Princess Class locomotives were some of the most prestigious and powerful express passenger engines to run on the London, Midland and Scottish Railway.
Designed by Sir William Stanier, these impressive Pacific locomotives were introduced in 1933 to haul the LMS’s most important long-distance passenger services.
With their strong 4-6-2 wheel arrangement, large boilers, and elegant appearance, the Princess Royal Class locomotives established themselves as some of the finest express engines in Britain. One of the most famous of these was No. 6201 Princess Elizabeth, which became well known throughout the LMS network for hauling major express services.
During the golden age of model railways, companies such as Milbro produced meticulously engineered O Gauge locomotives that allowed enthusiasts to recreate the drama of Britain’s great express trains on their home layouts.
This O Gauge electric model of the LMS Princess Class captures the character and style of the real thing. Complete with tender and designed for 3-rail electric operation, the model allowed collectors to run a miniature version of one of the LMS’s most famous express engines.
Today, Milbro locomotives are admired for their craftsmanship and have become increasingly desirable among collectors who appreciate the engineering quality of early British model railway manufacturers.

Behind the Scenes
Milbro locomotives featured practical design and sturdy engineering. Built for frequent use on model railway layouts, they were constructed using durable metal components and finished with resilient coatings.
During this period, many O Gauge railways utilised a 3-rail electric system, which ensured reliable electrical contact and smooth operation, enabling enthusiasts to create increasingly realistic layouts on which locomotives could run continuously.
Models such as the Princess Class locomotive demonstrate the transition of model railways from simple toys into more sophisticated mechanical replicas, capable of recreating the excitement of real railway operations.

Mike’s Personal Note
The LMS Princess Class locomotives have always impressed me. They were powerful engines and looked every bit the part when hauling the LMS’s most essential express trains.
The Princess Elizabeth is probably one of the best-known locomotives of the class, and seeing a model of it in O Gauge always brings to mind the great mainline expresses of the LMS era.
Milbro produced some very resilient locomotives, and this one is a good example of their engineering. The Pacific wheel arrangement with tender gives the locomotive real personality, and when running on a layout, it looks exactly as an express engine should.
What I particularly enjoy about these 3-rail electric locomotives is watching them glide steadily around the track once they’ve been properly serviced and set up. It’s a reminder of how well these models were made and how much enjoyment they have brought to collectors over the years.
Whenever I come across a Milbro locomotive like this, I always take a moment to admire the craftsmanship. They are wonderful pieces of model railway history, and it’s always satisfying to see them go to collectors who appreciate their story.
Talking to other collectors and enthusiasts is always a pleasure. You can leave a comment or drop me an email.
