Kadogosa: Tumetumia umeme wa 336,000 kwenda na kurudi Dar - Morogoro

Uongo vipi wakati treni lina mita ya umeme
Kashusha gharama za umeme uliotumika, labda usiwe na uelewa na issue za motor ndio utakubali huo ujinga anaousema.
 
Tunataka technical report in terms of speed, tonnage, safety, economic aspect of it as compared to the former ...and the like. Siyo story za layman kama hivi ...

How much electricity is consumed by an electric train?

Trains, as a whole, are very efficient way of transporting passengers and good. This is the outcome of the fact that friction between rails and wheels is very low (unlike tyre and road) and thus energy required to keep the load in motion, once it has already set in motion is quite low.

As would be evident from above, the total amount of energy required for different types of trains is different. For freight trains which usually move long distances in one go before being pulled into siding for long hours for letting other trains pass by, the consumption of power is quite low. For long distance express trains which have relatively more stops, the consumption is comparatively high. For passenger trains or local trains which have stops every few kms the consumption is very high.

Since the length (and thereby weight) of trains varies considerable, rather than saying a particular class of train has so much consumption, IR generally uses a metric called as Specific Energy Consumption. The unit of SEC is GTKM or Gross thousand Tonnage per KM, which means that the energy mentioned is basically the no. of units required to move 1000 tonnes of load per km.

following are the figures for different classes of trains in units consumed for moving 1000 tonnes per km:
Goods train: 6–7 units per GTKM
Mail/Express train: 17–19 units per GTKM
Passenger trains: 26 units per GTKM
EMU (local trains): 40 units per GTKM
 
Tuhesabie speed yake.
 
Wamechukua muda sababu....hawawezi enda full speed...kwenye test....mdogo mdogo test ya pili wataongeza speed kidogo.....test 3 etc....then wataweka constant speed wakianza safari biashara
 
Mainjinia wetu watuwekee mahesabu ya unit sasa... Jamiiforum Huwa kuna vichwa vya hatari walipata A+ kule chuo kikuu. Sasa wekeni formula hapa ya ku-calculate electrical power consumption tulinganishe na taarifa ya mkurugenzi ya gharama.
Mimi sio mhandisi

Wametumia masaa manne kwenda na kurudi morogoro , speed ambayo nadhani ni karibu na full speed ya hiyo treni
Lakini kama kadodosa ametoa hizo figures ilhali hawajafanya full test at full speed and maximum allowed weigjt basi atakuwa hayupo sahihi.
 
I am not an engineer, but with modern sources of knowledge, one can gather as follows. Kadogosa should present something like this

sasa yeye hakuwa na mizigo wala abiria katika train yake ya majaribio, he can not say anything about economic gain from this early test!
 
Ilibeba abiria kiasi gani? Matumizi ya umeme yanayegemea uzito uliobeba. Asije akafikiri umeme unaotumika kuendesha treni tupu ni sawa na ule wa kuendesha treni ambalo lina full load.
 
Hapo halikuwa na abiria kivile limekula umeme Ivo sasa ngoja liongeze mabehewa libebe na abiria uone umeme wake utakuwaje, bado linakula umeme Ilo kwa kuliangalia tu Kwanza lizito.
 
Ameongeza kuwa, upatikaaji wa mizigo mingi utachangia kupungua kwa nauli kwenye treni ya abiria na kufanya watu wengi wawe na uwezo wa kumudu bei za kupanda treni hiyo.
 
Kama mkurugenzi anasema gharama ya nishati ni ndogo na lengo ni kupata pesa kupitia kubeba mizigo, kwanini usafiri huo kwa abiria usiwe bure kabisa au ukawa sawa na bure kabisa (labda buku) ili watanzania wengi wafaidi matunda ya kodi zao?
