	Railway transport is a primary asset to trade, industry and commerce development of nations hat demand among others, a safe transit and optimal maintenance. Track performance remains an important index towards measuring track degradation. Thus, in this study the rail track geometry model was adopted to analyze the quality of Iddo – Mushin rail corridor towards safe rail transport system. Geometric parameters of interest include vertical irregularities, horizontal irregularities, cross-level, twist and track gauge. The parameters were calculated from a 3-dimensional data collected using Tachymetric Surveying approach covering Mushin, Yaba, Ebute-Meta and Iddo terminus. It should be noted that despite the high standard used as regards to the design and construction of the Iddo-Mushin rail track facilities, several derailments have occurred over time due to rail geometry deformation with high probability incidents along the Iddo – Ebute-Meta corridor. It was also discovered that the Iddo-Mushin axis can only permit average train speed of about 80 km/h, using the Polish Railway Synthetic Coefficient for safe rail transportation system. The synthetic assessment approach is simple and facilitate a continuous measurement of geometric parameters along railway track. Proper maintenance and upgrade of the rail track system mechanisms to support the incremental trasport demand and services as a result of socio-economic growth and development of Lagos mega city,
	is therefore suggested.
