The Dashed Line

The air at Addis is thin at 6 a.m. and the wing outside 5A is still cold to the touch. On the tarmac, heat has not yet arrived to make a mirage of things.

Two rows ahead, a man holds his phone too bright. It is a map of Africa, not political but technical, laced with colors. Thin lines in mustard and rust and blue. In the corner, a key. Someone has asked what U/C means.

It means under construction.

That is the whole answer, and it is not enough.

The map he is looking at is the map of gauges. For a century, Africa's railways were not a network. They were a series of arguments from the coast inward. The British laid 1,067 millimeters, the so-called Cape gauge, narrow enough for tight curves through hills. The French preferred meter gauge, a full 67 millimeters narrower, which is a small difference until you try to move a freight car across it. The Germans, and later everyone else, insisted on standard gauge, 1,435 millimeters, as if standardization itself were a moral good. The result is a continent stitched in different widths, as if sewn by different tailors who never met.

You can see it from above, or rather, you cannot. From 35,000 feet, there is no gauge. There is only dust and green and the occasional straight scar that resolves into track. The incompatibilities are invisible, which makes them easy to forget.

U/C is a cartographer's courtesy. It says: this line does not exist yet in steel and ballast, but it exists in intent. It exists in budgets and bilateral agreements and feasibility studies. On many maps it is drawn as a dashed line, which is a beautiful convention. A dashed line is both there and not there.

There are a lot of dashes now. The Standard Gauge Railway from Mombasa toward Nairobi and then, on paper, onward to Naivasha and Kampala and Kigali. The line from Kano to Maradi across the Niger border. The rehabilitation of the Benguela line, the extension in Tanzania, the long-talked link between Isaka and Kigali. Some are being welded a kilometer at a time. Others have been under construction in the imagination for twenty years.

It is easy to be cynical about a dashed line. Easier still from a window seat, where you are moving at eight hundred kilometers an hour without touching ground. But there is something stubborn and moving about a continent that continues to draw itself in future tense.

In Europe, a railway map shows what is. In Africa, a railway map has always shown what might be. The first colonial maps showed lines deep into interiors where no surveyor had walked. They were speculative fictions that then required forced labor to become fact. The new maps are different in authorship, not in optimism. They are still promissory notes.

I once took the old Nairobi to Mombasa night train, the one on the old meter-gauge that swayed so badly you learned to sleep with your knees braced. It took all night and part of the morning. Now there is a new line, standard gauge, Chinese-built, four and a half hours, with airline-style seats. On the old map, that new line was U/C. Now it is a solid line. People complain about the price and the timetable and still take it.

That is the quiet work of U/C. It holds a place for a future without guaranteeing it will arrive on time.

The man two rows up zooms out. The whole continent fits in his palm, cut by colors. Mustard, rust, blue, and those hopeful dashes. The cabin chime sounds, a soft, familiar bing, and the captain says we are beginning our descent. The wing tilts. The dashed lines disappear into cloud.

I put my own map away, which is mostly blank.
