eti there is no way I can argue... ...
Anyway, Typical tanzania way of argument.. based on rumors, heresy and not facts... last time it rained was this year, and it was the worst floods in 10 years and not one of the 472km of SGR line failed..... The incident you are talking about happened in 2016 when slop protection on parts of the sgr were not even done, the drainage too... if you go and take a look at the pictures that were taken you will see a chunk of the slop was still just bare sand with no slop protection...
if builng high emberkment was about snow railways in the whole of EU would be high above ground.. Russia has the 2nd largest rail network...and that country is half snow....but their rail is not high.
And as for the main point, your Rail is bieng designed to AREMA standards ... as as far as that is concered, its the most outdated standard of all the standards used by different countries.. Do you know how many KM of rail the Americans have built in the last 50years since you gained independence? infact, once Tz finishes building its SGR, you will have more electric rail than the US! Arema technology has not been updated in the last 70 years...
While on the otherhand, the chinese learnt how to build railways from the americans, they later took everything that Arema offeres and improved on the technology and improbed on it.... the chinese standard is actually safer, more robust and more durable than Arema... That is a scientific fact!
