SGR Construction in Tanzania - UPDATES

Kaka acha kupiga ramli, sasa huna reference zaidi ya huyo Mganda?, Mbona serikali yenyewe ya Uganda ilichagua kujenga electric kutoka na gharama za uendeshaji kuwa chini kuliko diesel, ina maana hawakuliona hilo?. Unapotakiwa kutoa credible reference sidhani kama reference ya hear say inakubalika, hivi vitu vya maintainance cost ni vitu vya kitaalamu ambavyo vinakuwa available for public consumption, Kama umeshindwa kutoa original source yake, basi nyamaza hoja yako sio kweli na haina mashiko.

Railway yoyote inapimwa kwa vigezo vifuatavyo ili kupima ubora wake (Superiority)
1)Safety
2)Speed
3)Modernity
4)Capacity(axle size)
5)Electric Vs Diesel
6)Running costs

Katika maeneo yote hayo onyesha ni wapi Kenya inaweza kujilinganisha na Tanzania?

Kwenye capacity tunawatoa meno

Hahaha, katika hili eneo la SGR bora uwe mpole tu, Tanzania train uwezo wake ni 35 tonnes excel, Kenya ni 25 tonnes only
Railway Under Construction in Tanzania Probably Africa's Best

Ndii anawaambia kila siku wameibiwa wanabisha alitoa mfano how many trips the cargo trains that can't be longer than 1km need to make to reach the 35 mln tons. The calculations couldn't add up! While Dar to Morogoro is 205 km, has 6 stations that each offer route exchange of a 2 km train long aside 95 km parallel route decicated just for that! U can't say of the same for Kenya's SGR.

Wakati mwengine huwa ninajiuliza hawa wakenya haya mambo ya hovyo yanayofanyika nchini kwao na wanadanganya na viongozi wao mchana kweupe na wanakubali, ni kwasababu uwezo wao wa kuelewa mambo ni mdogo au wanafanya makusudi kwa kubebana kwa sababu za tribalism?, kwasababu mambo yako wazi mno kuona nchi yao inavyopelekwa kihuni.

Ukabila "our time to eat mentality" inawasumbua! Wengi humu ndani ni Wakikuyu! So usishangae wanachoandika ni katika kulinda maslahi ya central Kenya.

Too much knowledge is an agony...I think u don’t even understand what maintaining cost they r talking about, I advice u to go and read again....about the diesel consumption in Tanzania wont be the same as Kenya cause u will be importing much..there will be a huge difference of someone who is using what is produced in his country than someone who is using what is not producing...Your operation cost will rely on dollar fluctuation since your importing diesel...It does not take a genius to understand that

Ahaaa haaa haaa
Saaafi
The new thing I got regarding Kenyan SGR.
 
SGR project gains tempo as rails arrive at Dar port
ippmedia.com/en/news/sgr-project-gains-tempo-rails-arrive-dar-port

September 2, 2018
The first such consignment of rails, which have been imported from Japan, will be used in the construction of the rail stretch from Dar es Salaam to Morogoro.

He said the rails would soon be transported to the site ready to be fixed on the concrete sleepers.

According to the manager, the rails have been imported from Japan because the country was well specialized in their manufacture.

“People must be surprised that the rails have not been imported from Turkey, the country undertaking the SGR construction. Japan is globally renowned for the supply of quality rails and has been manufacturing rails for a long time,” he said.

He said that unlike the metre gauge railway, the new SGR rails will be of 120 pounds to enable them adequately withstand bulky weight.

Commenting on the progress of the project, he said it was at different stages of development, such as precast girder production, cutting and filling of gaps to make a level surface, and production and supply of concrete sleepers.

According to the manager, the project had reached 22 per cent, noting that at that pace he was optimistic they would meet the deadline.

For his part, TRC executive director Masanja Kadogosa said despite some challenges, such as this year’s heavy rains, they were moving at a satisfactory pace to ensure work was completed on time.

“I have consulted the contractor to have a recovery programme to compensate for time lost during the rainy season in some parts of the railway line," he said.

Tanzania signed an agreement with Turkish and Portuguese firms to construct the Dar es Salaam- Morogoro stretch at Sh2.7 trillion, which will be completed by November 1, next year.

Turkish firm Yapi Merkezi, through a joint venture with Portuguese company Mota Engil, won the first phase construction contract under the Tanzanian Railway Modernisation Programme worth $1.2 billion.

The firm is undertaking a 422-kilometre high-speed electric standard gauge railway line from Dar es Salaam to Dodoma, the longest section of the project, which has been divided into four phases.

Yapi Merkezi is currently implementing the first and second phases of the project from Dar es Salaam-Morogoro-Makutupora in Dodoma at a cost of $3.12 billion.

The firm is also responsible for technical, design and construct of the railway line, according to Reli Assets Holding Company officials.

Tanzania is said to have requested the Turkish state-owned Export Credit Bank (Eximbank) to help finance the 400-km stretch of the new railway, which is also being funded by the government of Tanzania.

The construction of the project is divided into four parts and put out separate tenders to design it. The three remaining sections are Makutupora-Tabora (294 km), Tabora-Isaka (133 km) and Isaka-Mwanza (248 km).

Tanzanian state-run railway firm Railway Assets Holding Company is expected to award at least one more contract before the end of the year, with the others slated for early next year.

The country plans to spend $14.2 billion over the next five years to build the 2,561-km standard gauge railway connecting its main port of Dar es Salaam to land-locked neighbours, including the Democratic Republic of Congo, Rwanda and Uganda.

In July 2016, China, through its Exim Bank, agreed to advance Tanzania $7.9 billion for the railway project, despite its key contracting firms having been omitted from the project.

Dah!! hata kama wewe ni mpenda kenya basi kuna kitu unatakiwa ujifunze. Hebu soma hapa kidogo:-


  • Electric Locomotive vs Diesel Locomotive The major advantage of the electric locomotive engine over diesel engine is that electric engine uses a rather simple and straightforward technology. The electric engine pulls power directly from the power grid and requires only a transformer and a regulator to bring down the power to acceptable levels. Diesel engines on the other hand uses diesel to produce energy, which is then transformed into electricity, and then again into kinetic energy, making them only around 40 percent efficient for the diesel consumed.
  • Electric Locomotive v/s Diesel Locomotive Technology Electric engines are lightweight, constituting only motors and wheel axles, and have almost no moving parts. Diesel engines on the other hand have a large number of moving parts such as pistons, valves, turbines, and chains. Electric engines are therefore easier to maintain whereas the moving parts of a diesel engine require constant maintenance.
  • Electric Locomotive v/s Diesel Locomotive Speed The simple nature of the electric engine makes them efficient and powerful. Electric engines do not produce much heat and noise, meaning that most of the energy produces converts into foreword motion. Diesel engines, on the other hand waste generate much heat and noise, diverting the energy away from forward motion.
  • Electric Locomotive v/s Diesel Locomotive Commercial Consideration A major commercial consideration for railways to prefer electric locomotive engines to diesel locomotive engines is cost and availability of diesel. Diesel is an expensive non-renewable fuel source whereas electricity is a cheaper and infinite source of energy.

Nashukuru kwa ELIMU hii mujarabu.
Awali nilifikiri diesel engine inafanya KAZI kama magari yanavyofanya KAZI. KUMBE inatumika kuendesha generators ambazo zinafua umeme kwa ajili ya kuendesha umeme!
The Kenyan SGR can be adopted to use a gas. It's more efficient to produce electricity using a gas than diesel. We can negotiate to pipe it to Kenya.

In electrical SGR the wagons r moved through electromagnet power found on the overhead cables. Sometimes the rails bars too are electromagnetized though overhead cable is a more reliable n economical viable. The good thing is mtambo wa gongo (diesel engine) can also use electrical SGR infrastructure.
