The Mak Itam

Almost every great Indonesian train journey is on Java. This one is not. It is on Sumatra, in the cool green highlands of the west, and it is unlike anything else in the country: a wood-and-coal steam locomotive, nicknamed Mak Itam — "black uncle" in the local Minangkabau tongue — that still fires up in the old Dutch coal town of Sawahlunto.

Mak Itam is the last survivor of one of the world's most extraordinary lost railways. To bring coal down from the Ombilin mines to the sea, Dutch engineers built a line up from the coast at Padang and through the Anai Valley on 35 kilometres of rack — a toothed third rail that a cog on the locomotive grips to haul it up grades as steep as 1 in 14. For most of a century, black E-class cog engines like this one climbed the gorges with their loads of coal, through jungle and past waterfalls, over a mountain summit and down into the mining bowl of Sawahlunto.

The mines are quiet now, and the coal trains have stopped. What remains is a UNESCO World Heritage landscape — the mine, the town, the railway and the port that shipped the coal — and, at the centre of it, a single black locomotive that occasionally steams again on the short surviving stretch of track. This is not a slick tourist railway; it is a fragile, moving relic in a town that has turned its whole hard history into a museum. But for anyone who loves trains, or wants to see the side of Indonesia the guidebooks miss, Sawahlunto and its black uncle are worth the long trip to Sumatra.

To understand Sawahlunto, start with the coal. In the mid-nineteenth century a Dutch mining engineer found rich seams in the hills of West Sumatra, and from 1888 the colonial government opened the Ombilin mine to work them. Coal, though, is heavy and the sea is far, so between 1891 and 1894 they built a railway to carry it — up from the port at Padang, through the Anai Valley, over a summit at Padang Panjang, past Lake Singkarak and down at last to the pithead at Sawahlunto.

It was a mountain railway of the boldest kind. The Anai Valley climb was too steep for ordinary adhesion, so the engineers laid a Riggenbach rack — a ladder-like toothed rail down the middle of the track — for some 35 kilometres, with gradients reaching 1 in 14. To work it they ordered special locomotives: the E10 class, squat black 0-10-0 rack tank engines built by Esslingen in Germany, the Swiss Locomotive Works, and later Nippon Sharyo in Japan, with an extra set of cylinders driving the cog. Thirty-nine were built over half a century. In the Minangkabau highlands they earned an affectionate name — Mak Itam, "black uncle" — and for generations they hauled Ombilin coal down to the steamers waiting at Emmahaven, the port now called Teluk Bayur.

The men who dug the coal did not come freely. The mine ran on the labour of some twenty thousand convicts, shipped in from across the Indies and known locally as the Orang Rantai — the "chained people", who worked the seams in irons for a few cents a day. Their story is written frankly into the museums of Sawahlunto today, and it is part of why this is such an unusual heritage site: it does not pretend the coal came cheaply.

The line worked into the 1980s, then faded as the coal ran down; the last of it closed when the mine finally shut in 2003, and the rack sections through the Anai Valley — the spectacular heart of the journey — have carried no trains for years. What survives is a short stub at Sawahlunto, from the town down to Muaro Kalaban, a few kilometres of the old line. On this the town keeps its steam alive. E1060, one of the black rack engines, was fetched back from a museum on Java, patched up, and now — on a good day — raises steam again to trundle visitors down to Muaro Kalaban and back. It is a modest ride on a fraction of a once-mighty line. But when the whistle blows and the black uncle moves off between the green hills, you are watching the last living breath of a railway that once climbed a mountain full of coal.

Be honest with yourself before you plan around this train: the Mak Itam heritage service is an informal, occasional operation, not a scheduled railway. When it runs, it runs like this:

The round trip covers only the surviving ~4 kilometres of line between Sawahlunto and Muaro Kalaban, takes well under an hour, and costs a token fare — around Rp 50,000 per person at the last report. One coach, a few dozen seats.

A few important cautions:

• It is unreliable. Keeping a century-old rack locomotive in steam is hard; parts are scarce. The service has stopped and restarted more than once, and on many running days a diesel locomotive dressed in vintage livery hauls the train while the historic E1060 stays in the shed as a static exhibit. If seeing (or riding behind) the real steam engine matters to you, ask locally first — through the Sawahlunto tourism office or KAI Wisata — and treat any steam day as a bonus.
• You cannot ride the famous rack sections. The spectacular climb through the Anai Valley and the run along Lake Singkarak — the scenery that made this line legendary — no longer carry passenger trains. The stretch beyond Muaro Kalaban toward Padang Panjang has been closed since 2014. What you ride today is the short town end only.
• There is no through train to Sawahlunto. To reach it you travel to Padang (which has an airport with rail links) and continue by road into the highlands.

For context, West Sumatra does still run regular trains around Padang — the Minangkabau Express airport link, the Pariaman Express up the coast, and the Lembah Anai railbus — which are useful for getting into the region even though none reach Sawahlunto itself.

Details as of the 2026 season and subject to change. The heritage train's operation is weather- and maintenance-dependent; always confirm locally before travelling.

The Mak Itam heritage train is run jointly by KAI Wisata (the tourism arm of Indonesia's national railway) and the Sawahlunto city government, and it is very much a local operation. There is no online booking: tickets are bought on the day, at the station, for a token fare, and the best way to confirm whether a train — and especially the steam locomotive — will actually run is to contact the Sawahlunto tourism office or the museum in advance.

Sawahlunto's museums (the Railway Museum in the old station, the Mbah Suro mine tunnel, and the Goedang Ransum museum) are open most days and charge only small entry fees, so a visit is rewarding even without a train.

Getting there is the bigger planning job. Fly or take the train to Padang, then continue by road — roughly three hours — up into the highlands to Sawahlunto, ideally combined with the other Minangkabau sights of Bukittinggi, Lake Singkarak and the Anai Valley.

Sawahlunto is the destination, and it is a remarkable one — a Dutch colonial coal town preserved almost whole in a steep green bowl, presented now as a living UNESCO World Heritage site. Give it a full day; the mine museums alone will take most of one. Do climb to the hillside viewpoint while you are there, for the classic look down over the red roofs, the mine headframe and the "SAWAHLUNTO" sign on the slope.

Beyond the town, the old railway pointed straight at the finest scenery in West Sumatra, and you can still follow it by road.

Sawahlunto itself is small, and its accommodation is modest but characterful. The town has turned several of its historic buildings to new use, and the most memorable places to stay are the heritage guesthouses and homestays in the old colonial quarter — simple, friendly, and steps from the station and the mine museums. There are a few basic hotels for the rest; this is a place you come for the history, not for luxury.

Many travellers, though, base themselves in the wider Minangkabau highlands and visit Sawahlunto on a day trip. Bukittinggi, the region's main tourist town, has by far the widest choice — from backpacker guesthouses near the clock tower to comfortable mid-range hotels with views over the Sianok canyon — and makes an excellent base for the whole highland circuit of lakes, valleys and villages.

At the coast, Padang — your likely arrival point — has the full range of city and business hotels, useful for a night on the way in or out. Wherever you stay, book ahead around Indonesian public holidays and the long Idul Fitri season, when the highlands fill with domestic visitors; and if you are timing your trip around a possible run of the Mak Itam, aim for a Sunday and confirm the train locally before you commit.
