Nilikuambia not everything is worth having issues with...Kwani mnashindwa kuweka ramp?
kwahiyo unaridhika na kilichopo kwa gharama ya $200 mln of modernization?Nilikuambia not everything is worth having issues with...
And FYI! Ramp ni huo mlango wa wagon nusu unafunguka kuja chini, look carefully at the chain link holding the door/ramp when it's on the ground.
You are confusing Naivasha - Kisumu-Malaba MGR which goes to the west of Kenya with this 240km Nairobi-Nanyuki railway which heads north of kenya. Nanyuki is only 70km from isiolo town (remember isiolo frI'm the lapsset project?)kwahiyo unaridhika na kilichopo kwa gharama ya $200 mln of modernization?

Why are we using 50kg/m rails and not 60kg/m?
Tue, 03/20/2018 - 06:41 -- sgradmin
a) The 50kg/m rail section is sufficient and cost effective for the projected traffic bearing in mind that rails wear and tear and are replaceable.
- Although the preliminary engineering (by Gauff Consultants) had proposed 60kg/m, the NCIP SGR protocol required us to use 50kg/m.
- The Chinese standards TB 10082-2005 code for design of railways track specify that if speeds are 120kph and tonnage between 15-25 million tones (converted density volume), the 50kg/m is sufficient.
- The formula for sizing rails clearly show that 50kg/m is appropriate from the scientific point of view.
- The rail size (weight per meter length) is determined primarily by the axle load (other factors include traffic density, speeds etc.). The NCIP regional SGR axle loading is 25 tons which requires a 50kg/m rail.
- The wear and tear on these rails is a function of traffic density. The traffic density of Mombasa – Nairobi will be much higher than that of Malaba – Kampala, which is why Kenya decided to use larger 60kg/m rails. About 70% of the Mombasa port traffic is destined for Nairobi area.
b) As good practice, rails are replaced after they have worn out and lost 5% of the weight.
c) Generally the rails constitute about 1.3% of the cost per route-Km.
d) 50kg/m rail is a common rail section used in China and therefore replacement rails are easily available.

Ongezea na hizi basi. This is not SGR BTW
Kwa t@ko la nyanyakoIzi akili mafiii huwa mnatoa wapi?
endelea kujidanganya!Tanzania mpo wapi na Dar+Tanga+Mtwara+Zanzibar port zenu ?
Your best performance is worse than what we were doing back in 2010 and 2011

Mbona gazeti la East African hua linapenda kuchapisha headings za ku hype zinazofanya watu wanunue gazeti, kama "Dar port takes business from Mombasa port" mara sijui "Uganda prefers Dar port over Mombasa" .... Heading za click bait hizo, There is no competition between Dar and Mombasa port! Mombasa port is clearly the dominant port even when hands tied and blind folded !!!!
