Kenya Railways Explains Length and Destinations Served by MGR and SGR

Kenya Railways has moved to clear up widespread confusion among commuters over the actual difference between the Meter Gauge Railway (MGR) and the Standard Gauge Railway (SGR).

The two networks, though both run under the same corporation, are built on completely different track widths and serve different purposes across the country.

The key difference between the two is that MGR trains run on a narrower track measuring one metre wide, while SGR trains use a wider track measuring 1.435 metres.

This difference in width is exactly why an MGR train cannot simply switch onto SGR tracks, or the other way round, without special equipment.

Kenya Railways explained that MGR refers to the country’s older railway network, the Kenya-Uganda Railway, which was built between 1896 and 1901 and has served generations of travellers for decades.

SGR, on the other hand, is the newer system, purpose-built for speed and designed to move both people and cargo faster across the country.

Another key difference is that the MGR stretches an impressive 2,046 kilometres across Kenya, dwarfing its younger counterpart, SGR, in sheer coverage.

The MGR links major towns such as Nyahururu, Kisumu, Nanyuki and Malaba, connecting communities that have relied on rail transport for years.

One standout example is the Nanyuki MGR line that was rehabilitated recently, which was recently rehabilitated, covering 755 kilometres from Shimanzi in Mombasa.

The Kisumu MGR line has also been restored, reconnecting central and western Kenya to the Port of Kisumu to support regional lake trade.

Elsewhere, the Riruta to Ngong commuter line, a 12.5-kilometre stretch, is under construction to ease the daily traffic headache along Nairobi’s Ngong Road.

By comparison, the SGR covers just 592 kilometres, but its Mombasa to Nairobi line cuts a journey that once took hours down to about five.

An extension now runs from Nairobi to Suswa and Naivasha, adding another 120 kilometres and featuring an inland container depot for cargo handling.

Key Differences With Other Countries

Kenya’s coexistence of Meter Gauge Railway (MGR) and Standard Gauge Railway (SGR) reflects a global pattern. Many countries operate multiple gauges because networks were built at different times, due to colonial systems, engineering considerations, or economic circumstances.

India historically operated broad gauge at 1.676 metres, metre gauge at one metre, and narrow gauges of 0.762 and 0.610 metres. Through Project Unigauge, authorities are converting many metre- and narrow-gauge lines to broad gauge.

Australia has standard gauge of 1.435 metres, broad gauge of 1.600 metres and narrow gauge of 1.067 metres, while Spain combines 1.668-metre Iberian gauge with standard-gauge high-speed lines. South Africa mainly uses 1.067-metre Cape Gauge.

Japan generally uses 1.067-metre narrow gauge on conventional lines, while Shinkansen uses 1.435-metre standard gauge. Kenya’s one-metre MGR and 1.435-metre SGR coexist, illustrating historical legacy, with modern projects increasingly favouring standard gauge internationally.
