The biggest design error will be to install a single track. An intercity track can never be single track as it beats the logic when only one train has to go through a section. Remember there will be an exponential growth in rail passenger usage and we do not want to be redoing a new project in 10 yeras time when we realize that a single track is the greatest bottleneck to infrastructure capacity. You would rather build a short section with a double track as the returns will be unimagined.

Yeah..
It's kinda weird building a single track railway but there will be 40 stations over a distance of 485 km. That will make up for everything over the short term.

Considering the size of the project, the costs and how the traffic needs to build up I can see why one would do single track, especially with 40 stations on the route that (I assume) all will have passing tracks. Sweden has newly built single track railways (up in the sparsely populated north), but those parts aren't expected to have the kind of traffic increase we all can see happening in Kenya.
So... Sure, build it mostly single track now (with passing tracks) but if they don't prepare bridges, tunnels, rights of way and such for double tracking that would make very little sense.

Depends of the money available...

How much additional cost comes in from building the platform for a double
track right from the start ? Knowing that for security reasons, double-track
tunnel bores are not very much in favor those days ? How does it compare
with building for single track and enlarging later if required ?

On the other hand, those days, with enough passing loops and centralized
traffic control, it's amazing to see how much traffic can be done with one
track only...

Well, they don't have to build everything but the second track, the minimum would be to have the plan for how the second track will fit in ready and make sure nothing being built now will make double tracking harder and that nothing gets built where the next track will go.
Tunnels and bridges area a special case though. Like you said having one bore per track is common now and just making sure the space the second bore will go is kept free of other works would do wonders. The same for bridges: either build it wide enough for two tracks and use the empty space for a small road (maybe not open for cars) or make sure there's space to put in a parallel bridge later.
Making sure one isn't messing it up for one's future self doesn't have to cost any real money (though you can always do more prep-work if you've got the money - but if you do, why not put in a few more passing tracks?)

Concrete Sleeper factory and skills transfer

Looks like there's some skills transfer going on.



mostly Kenyans working in the sleeper factory, according to megaprojectske, most have undergone training....hopefully there's also some Kenyans trained for managerial roles at the factory.



apparently this girder was built by Kenyans too.

Clearly there's some measure of skills transfer going on....but again hopefully some of the more complex engineering aspects are being taught to Kenyan engineers

This is how massive girders are



Sleepers per Megaprojects 638 made so far. Production speed has been increased to meet demand.

Here is a YouTube video from September 2014 about a section of.the meter gauge network that was taken over by the principal shipper due to poor service from the government railway. As part of the deal, the private operator receives a subsidy from the government to continue to provide passenger service to isolated villages along the way and even deliver water to these villages.

http://youtu.be/h6K0uYU_zUg

It shows the condition of the meter gauge trakage compared to the new standard gauge railway.

From Rail Journal:

Second stage of Kenyan new line to start in July
Monday, February 02, 2015



CONSTRUCTION of the second phase of Kenya's new standard-gauge railway from the capital Nairobi to the Lake Victoria port of Kisumu will start in July

This is a change in government policy because it was originally intended to first build the section from Nairobi to Malaba on the border with Uganda. However, the National Treasury now favours building the 398km line to Ksumu first because it says Kisumu has the shortest access to other East African countries using ferry links across Lake Victoria
