honestly that new KR MD will not really change much. We celebrated when Manduku was appointed MD of KPA, it didn't take long for him to be indicted in some corruption scandal... but let's wait and see.

True, I was very happy with his first six months at KPA. He even predicted he will turn the fortunes of tax collection at the port to rise high enough to pay off the National debt. Then greed got him and a whole list of corruption scandals emerged. His low point was hiring bloggers to cheer his achievements on social media. Kenya still has a long way from engraining honesty in our leaders.

I recommend reading these reports as policy makers will base their decisions on this

some weird assumptions (DMUs being cheaper than EMUs)

The consultants that compiled the report come from South Africa and it shows...

Good transit practice happens outside the anglosphere and looking at the literature and case studies used from other anglo countries (where they got their weird cost estimates from) u can see why...

They didn't even looked at Dakar TRE which is built using french standards to french operational practices at a cost per km way under the given estimates for each route in this report. This is basically a project with exactly the same preconditions and objectives as in Nairobi.

Edit: I stand corrected one of the consultants is Spanish

Track layout Nairobi Central



As can be seen in the above schematics they intend to turn every train at Nairobi Central which requires massive amounts of turning tracks just for no operational sound reason. Commuter rail systems all over the world do it exactly the other way and let their trains run through.



Copenhagen S-train network (Kobenhaven H being the equivalent of Nairobi Central)

Phases

The report comes with recommendations which stage to do first with and a cost plan for each year that is in the range of the current revenues of the railway development levy.

Frequency and track layout







It's weird that they propose new built single-track portions - single tracking new built sections is not really a cost saver...

Another study to go to the shelves.

To me the best transport report that should ever be implemented is the one done by JICA.

Why did they use 2009 population census stats, they could have used the 2019 numbers. There is a significant increase in the 10 years for population size.

The study was carried out from 2015-2018

You can model population estimates any time as long as you have a solid base. They could have used estimates from the National Statistics Bureau, they have reliable numbers for each year. That's my first substantive critique of the methodology. Volume is a key input in transportation models. And as always, garbage in garbage out works here. If you have bad/inaccurate inputs you'll get bad/wrong outputs. It's a good attempt though. Adjustments can be reflected operationally in frequency of trains or by adding seats per trip.

Second critique: It seems quite pricey. But good things cost money. I've been to the Washington DC metro and NYC subways and those things must have gobbled billions so no escape. We need it we should build it.

abckris, the base year they used was 2009. They then projected population growth based on KNBS data for the design period which was probably 20 years. How did you expect them to use 2019 data that wasn't there in 2015 when they started the study? The 1st thing you do when you commence any design, and I've been involved in many, is data collection and the 1st point of call is the census report. what was available then was the 2009 census report

New arrival date for 11 of 15 spanish DMUs is April as per PS Hinga. But this is Kenya govt, hopefully no delays this time around.

Old refurb trains but ill choose to look at the glass half full, they should be much better than the locomotives ones operation wise.

Shouldn't the rebalasting of tracks, drainage works and construction of mini stops be ongoing in preparation for the DMUs?

The DMU capacity looks low. They say a maximum of 3 sets can be coupled. Each set has 2 cars. I don't know how they will survive peak hours.

I have seen the Dandora and Embakasi trains during peak hours and its packed to the brim. The Locomotive normally pulls about 20cars.

Looking forward to all day service, not the morning and evening schedules they currently have. This should work wonders. Even looking forward to matatu crews picketing due to lack of customers, like the truckers after the SGR started hauling cargo

All along I thought the new JKIA line would pass through much of Eastlands. I was wrong. I had line 5 in mind instead of line 4 as the main JKIA line.
