Narrow Gauge Loco

About my railway

I'm building a railway in my garden. It's a narrow gauge railway, in 16mm/ft scale. In this scale, a model person would be about as tall as your middle finger.

As a result of moving house several times, I've built, and dismantled, three garden railways, and I'm currently building my fourth. Here is a brief history of the railways I've built.

The first railway

My first garden railway was an oval of track, screwed to creosoted scrap timber, and laid onto the ground in a rockery. This was fine in the short term, but it wasn't a particularly large oval. After a year or two, the plants in the rockery started to take over, growing between the sleepers. Sometimes this made it difficult to run a train. Also, the timber base was in contact with the ground, so it soon started to rot.

This railway was 45mm Gauge, and I'd decided to switch to 32mm gauge as that was what other garden railway folk in the area were running on, and I wanted to run trains on their lines, and invite them over. So, a decision was made to build a new line in 32mm gauge.

That said, it was very enjoyable, especially when there weren't plants all over the track. I could put a train down and leave it to run around the circle whilst I did some gardening. It seemed so right, to have the train appear from behind a rock and continue on its merry way, whilst I weeded a different part of the garden.

The second railway

The second railway was going to go around the garden at ground level. I cut a trench in the lawn, and laid a row of bricks on sand, trying to get the whole thing level. I enjoyed building it, but for the life of me, I can't remember why I didn't lay the bricks properly, on a sand-and-cement base (it would probably have been easier to get it level if I had!).

My Lego loco on a bridge I had built some rolling stock for my railway by this stage (you can read more about the loco here). I used it to test the line, and put screws and wall plugs in wagons as I went along fixing the track to the bricks. The loco wasn't very powerful as it didn't have much weight, and even though I thought I'd got the track level, the loco showed there was, in fact, a slope, a gradient. It wasn't level enough.

The circuit was about 1/4 complete in the spring of 2000 when, owing to a job move, I had to play Dr. Beeching 1, and lifted my entire railway. We decided to dig the first turf on the new Railway as soon as the dust and paperwork settled.

Lessons Learned from the first and second railways

The third railway; the MLLR

Whilst we were moving house, we planned the third railway. The 'directors' of the railway insisted on "some wiggles", and a "nice bridge", and the 'Engineering department' considered a number of interesting features to add, such as a "Gauntlet Bridge" 2. Various 'local people' (i.e. our friends) expressed a desire to see a "round-the-pond" service, for which a pond would be necessary, and a tunnel, for which the Directors sought expert advice on moving mountains, as the new terrain was not particularly hilly.

Diagram of the Maple Leaf Railway By May 2001 The new line had been designed and the groundworks were started. The intention was a complete circuit as per the diagram.

The black line is the trackplan. The green lines mark the raised borders (made of real railway sleepers). Between the two raised borders was a tree, and the line was to cross on a large bridge here (shown in red). Because of the lie of the garden, a rising loop was required. which would also add operational interest.

The balloon loop on the left of the diagram was constructed, as a circle of track. (see construction photos below) This would provide an initial running track, whilst the remainder of the line was developed. The line was tentatively called the Maple Leaf Light Railway, because of a large Maple tree elsewhere in the garden.

However, the remainder of the line did not get developed. Another job move in Summer 2002 meant ripping up the circle of track, boxing everything up and preparing to build again, from scratch.

Lessons Learned from the third railway


We knew that our new house would require some work doing to it, and that it would be a while before we got a chance to build a railway at the new place. We optimistically anticipated that we could start railway construction sometime in 2003.

So, before moving, I made a portable railway using second hand shuttering ply. It comprised 8 sections which made an octagon, with a circle of track screwed on. The aim was to be able to set it up quickly to be able to play trains, even before my new garden railway was ready, and I had hopes that once I started construction, the octagon could be converted into a balloon loop so I could get continuous running quickly.

However, plans changed, and a major house renovation project put railway construction on a back-burner. The octagonal plywood track was set up semi- permanently in the garden but forgetting to weatherproof it with creosote substitute did not helped its longevity. (Will I learn from my own mistakes?)

The delays in starting a railway have been a blessing in disguise, because they've given us more opportunity to design the railway, and work out what we actually want. On paper, the railway has moved about the garden quite a bit, and has changed design considerably. The portable track has been used on a number of occasions, and currently qualifies as the longest-lasting railway I've made (5 years).

Update: Autumn 2007, The plywood started to rot, marking the end of the portable railway. The trackwork went into the shed to be reused, and the plywood went in a skip we conveniently happened to have at the time.

Lessons Learned from the Portable track

The fourth railway

In 2007, the children and I started building the new, permanent railway in the garden. By the spring, concrete foundations had been cast, and bricklaying had begun. The aim was to have a circle of track on a brick base, from which the railway could be expanded at a later date.

By June 2008, the brick circle was complete, and I was able to start laying track. As I prepared the track panels, I realised some of them had already been used on three previous railways over the last ten years!

The circle of track was completed on Fathers Day, and the latter part of the afternoon was spent running a train. It even had some passengers, thanks to some toys from the children.

May 2010 update

The two years since the photo above were mainly occupied on other things. However, with the circle of track down, I was able to run a train again at long last. I also made a start with the track base for the rest of the railway.

Over the late May bank holiday in 2010, I built a tunnel and approach cuttings for the other end of the railway. The tunnel sides are constructed using patio slabs on edge set in concrete. More patio slabs will make up the top, providing a flat surface for another track to run over.

In the photo above, you can see the concrete track base which runs through the tunnel. That was cast in the summer of 2009.

I wanted to create the effect of a cutting either side of the tunnel. It just happens that there was a rockery in our garden when we moved in, and I'd kept all the rocks for exactly this purpose. Choosing ones with flat surfaces, and lining them up along the edge of the track base produced a cutting (and some sore muscles - those rocks are heavy! Do take care if you're going to try this yourself.)

You can see the tunnel towards the back of the photo, with a vertical slab covering the entrance.

To make sure the rocks were stable, I mixed up a slurry of mud and water, and sat the rock in that, a bit like mixing concrete and setting a brick into it. It felt like making mud pies in a bucket, but it enabled me to create a perfect "mould" of the rock for it to sit in, so it wouldn't wobble.

I suspect it'll be necessary to mix some mortar to fill in the joints between the rocks, otherwise all the soil will wash down the cracks and cover the track (when I eventually get the track in place!)

You'll notice that the tunnel isn't very long, and it's on a curve. Tunnels on a garden railway shouldn't be more than 2 arms lengths long, just in case you need to evict a hedgehog or a misbehaving locomotive. The fact that it's on a slight curve shouldn't be a problem. I still have to cut the top slabs into "keystone" shapes so they fit together properly.


The first loco I bought was a Lehmann Magic Train. I've modified it to run on batteries rather than having to wire up a controller to an outside track. I built a tender to house the batteries. This loco is 45mm gauge. It still gets played with, and I've made it child-safe by removing all the fiddly detailed bits which could get knocked off. I keep a circle of track of it to run on.

'Billy' is pictured left, and there's a photo of 'Ivy' here on Iain Maclain's Railway in Hertfordshire. Ivy is named after my Late Grandmother

I also inherited a Mamod 0-4-0 and converted it to Meths power. It's been banned from other club gardens, because it goes too fast, and it's a serious fire hazard. (I think this means I'll have to obtain a better regulator for it, and get a butane burner instead). The lovely light blue paintwork has been ruined by a Meths cab-fire. One of these days, I might get around to cleaning it up and getting it running again.

The Lego Loco in Harwich
My fourth loco is made of Lego 3. The chassis is an off-the-shelf electric one from Brandbright 4, and I built a prototype bodywork out of Lego. Other members of my local club thought it was rather good, so the bodywork has stayed. The Loco is now in Mark IV: I've added Lead weights inside the bonnet to improve traction.

I wrote an article for AWNUTS magazine describing the locomotive. You will find more picture here. She tends to pull some modified Binnie 5 Wagons.

Update! (2006) After several years of faithful service, Lego Loco is now in the workshops with drivetrain problems. There are higher priorities, so it may be a while before she's back in service.

Update (2010) A new chassis means the Lego Loco is back! Management will have to have a word with the maintenance depot about how long things take to get repaired!

  2. A Gauntlet Bridge is a bridge where two rival railway companies clubbed together to buy the one bridge. The bridge is only one lane wide, but the track layout is such that it is impossible to get onto the other company's rails. (An example of gauntlet track can be found here: the tracks interleave, but don't join or cross. In the case of this photo, it gets double track through a narrow cutting.)
