Bamako–Kayes Passenger Train

Single-track mainline with passing loops only at Kati, Kita, Bafoulabé, and Kayes — heavy freight priority on the corridor means passenger trains are typically held for up to 90 minutes at passing loops.

Crossing of the Bafoulabé escarpment requires a 1-in-50 (2.0%) ruling grade and minimum 150 m curve radius through the Bambouk / Bakoye River headwater gorge.

Bridges at the Falémé, Bakoye, and Baoulé rivers (all Sénégal River tributaries) are legacy steel-truss structures dating from 1902–1904, weight-restricted to 18 t axle load.

Laterite subgrade in the Sahel zone is vulnerable to washout during the July–September rainy season — speed restrictions of 20 km/h are common after heavy rainfall.

No modern signalling — train control is by verbal authority and paper orders at passing loops; CTC and ETCS are not installed.

Frequent 1–3 hour delays are typical due to freight-priority timetable (iron-ore, manganese, cement trains dominate the line).

Rolling stock is mostly 1970s / 1980s vintage with limited spare-part availability; SOPAFER refurbishment programme is in progress but capacity is constrained.

Sahel-zone sand drift across the track during the Harmattan (December–February) requires manual clearing at exposed sections near Nioro and Kayes.

Mobile-vendor boarding at principal halts (Kita, Bafoulabé) creates 20–30 minute dwell times, on top of scheduled stops.
