Why Tanzania’s Electric SGR Is Hauling More Cargo Than Kenya’s Diesel SGR — And Why It Stings

Kenya has always liked to brag: “We were the first in East Africa to build a modern SGR.”

But now Tanzania’s electric SGR has entered the chat — and suddenly, the bragging doesn’t feel that strong anymore.
Because when you look at what each train can actually pull… the truth hurts.

Let’s break it down in simple English.

1. Diesel vs Electric — This Is Where Kenya Lost the Battle

Kenya’s SGR uses diesel locomotives.
Tanzania’s SGR uses electric locomotives (25kV).

Electric trains are like a turbo-charged matatu — powerful, fast, and strong.
Diesel trains are like those old smoky buses—you get the job done, but slowly and with struggle.. 

 

Because of electrification:

• TZ trains pull more wagons
• TZ trains accelerate faster
• TZ trains handle longer trains safely
• TZ trains use less power per tonne

In short:
One Tanzanian electric locomotive can haul what two Kenyan diesel locomotives would struggle with.

That’s the first pinch.

2. Cargo Capacity — The Painful Part With Actual Numbers

Here’s where Kenyans feel the heat.

Tanzania Electric SGR (approx. industry-standard numbers):

• 40 to 60 wagons per freight train
• Each wagon carries 60–70 tonnes
• Total haul: up to 3,000–4,000 tonnes in one trip

Kenya Diesel SGR (using diesel freight limits):

• 20 to 35 wagons per freight train
• Each wagon carries 55–60 tonnes
• Total haul: 1,200–2,000 tonnes in one trip

So on the same track length:

👉 Tanzania can move double what Kenya can move
👉 Tanzania can clear a port faster
👉 Tanzania can offer cheaper cargo rates

And businesses ALWAYS follow the cheaper, faster line.

Picture the comparison:

TZ electric train:
Glides off smoothly with 50+ wagons like it’s nothing.

Kenya’s diesel train:
Growls, smokes, struggles… and pulls maybe 25 wagons.

The difference is painful even to watch.

3. Cost Per Trip — The Silent Blow

Electric trains are cheaper to operate because electricity costs less than diesel.

Meaning:

• Tanzania will offer cheaper cargo tariffs
• Shippers will prefer Tanzania by default
• More cargo will divert away from Kenya

This is no longer “SGR pride.”
This is business — and Kenya risks losing big money.

4. The Future-Proof Issue

Kenya built a diesel SGR in 2017.
The world had already moved to electric.

And now the consequences are showing:

Electric SGRs are:

• Cheaper to run
• Stronger
• Faster
• Greener
• Able to haul more cargo

Diesel SGRs?
They’re old tech dressed like new tech.

Tanzania built for the next 50 years.
Kenya built for yesterday.

5. The Part That Silently Hurts Kenya the Most

Every time Tanzania runs a long electric freight train with over 3,000 tonnes of cargo…
investors notice.
shipping companies notice.
the region notices.

And slowly, without shouting, the logistics industry starts shifting the centre of power eastwards — towards Dar es Salaam.

Because in cargo transport:

**Capacity is king.

And right now, Tanzania is wearing the crown.
