INFRASTRUCTURE forms the backbone of economic development,providing the necessary physical and social systems for sustained growth.

Once the fifth phase government under late President Dr John Pombe Magufuli and his assistant the then vice-president (president) Samia Suluhu Hassan came into power in 2020, among other things had heavily invested into multi infrastructures economic development sectors.

Few to mention among many including upgrading and improving of Tanga Seaport,expansion of Dar es Salaam sea port,signing contract with Uganda in the construction of East Africa Crude Oil (EACOP) pipeline from Hoima to Tanga which its implementation is at early stage of execution and construction of Julius Nyerere Hydro Electricity Power Plant(JNHPP).

Another state-of-the-art infrastructure project is the construction of Standard Gauge Railway(SGR) from Dar es Salaam to Mwanza,Kigoma lakeside ports and also connecting to neighbouring countries of Burundi and Congo DR.

According to economist by professional who spoke with this paper in an exclusive interview in Tanga,Dr Anthony Kimaro had analysed those mega projects implemented by government starting from fifth to sixth phase tenure said have not only economic benefits but also will have social,diplomacy as well as environmental impacts for number of decades to come from now.

 " The value of investment is given by the future consumption that is expected to yield,for the side of railway transportation,Tanzania has taken a major leap forward in its modernization".

" The development of rail transportation,Standard Gauge Railway(SGR) is significantly improving transportation connectivity for both transportation of people,goods henceforth making Tanzania Railway Corporation(TRC) operates two rail lines of meter gauge railway(MGR) and SGR"

He further pointed out that,this provide wide scope for haulers and business people for both of Tanzania and those from neighbouring countries of Burundi, Rwanda and Congo DR who offloading their transit goods at Dar es Salaam's TPA's port hub to opt either using SGR or MGR to transport their bulk cargoes to hinterland regions.

Recently,TRC introduced express passenger routes from Dar to Morogoro and later to state's capital city Dodoma,this came after the arrival of two sets of electric multiple-unit (EMU) trains and its coaches from South Korea.

The EMU trains named after late President Magufuli and current president Samia Suluhu Hassan,indicate their substantial contributions to the railway revolution in Tanzania.

According to Masanja Kadogosa,TRC boss said that those high-speed trains will slash travel time from 4 hours to at least 1 hour and 40 minutes from Dar es Salaam to Morogoro. A situation will regard time which is a crucial factor in economics.

While time is considered as an important factor in development,haulers,traders and other social sectors who are going to choose high-speed trains for their services,will experience a couple of benefits including that their customers will positively assess how their organisations and business firms perform efficiently and effectively.

Others are to reduce the cost of delivered goods,facilitate the physical mobility of people and products and increase competitiveness.

Still in the margins of the economy,SGR will help the TRC to improve productivity, expanding its employment scope by providing direct and indirect jobs,to attract more investments and enhance the overall well-being of their citizens.

" SGR could spur vital interactions within production,production costs and consumption in which every economic sector opt to spend it could reflect itself on that mirror for assessing themselves in their efficiency, productivity,competitiveness and effectiveness in delivering their services".

"Beyond its tangible infrastructure advancements, for its transformative impact, SGR will emerging as key pivotal of Tanzania economic ecosystem, nurturing growth in sectors starting from tourism, trade health services, agriculture, environment and education because will cuts costs into fares, freight, bolster trades and for environment will reduce carbon emissions as the rail using electrification
