Nairobi Matatu Route 33PM connects Nairobi CBD with Pipeline Estate through the Mombasa Road corridor.
The letters in the route number are particularly important. Nairobi has several Route 33 services heading towards different parts of the Embakasi area, and 33PM identifies the Pipeline service using the Mombasa Road side.
For commuters, this helps distinguish Route 33PM from services such as 33PJ, which also serves Pipeline but approaches it through the Jogoo Road corridor.
Route 33PM Quick Information
Route Number: 33PM
Route: Nairobi CBD – Pipeline
Main Destination: Pipeline

What Does Route 33PM Mean?
Route 33PM is one of Nairobi’s Route 33 variants.
The important part for commuters is the PM designation, which identifies the Pipeline Mombasa Road service.
This is useful because simply looking for a matatu displaying “33” may not be enough when travelling towards Pipeline or the wider Embakasi area.
Passengers should check the full route number:
33PM – PIPELINE
before boarding.
Where to Board Route 33PM in Nairobi CBD
Route 33PM operates between central Nairobi and Pipeline through the Mombasa Road corridor.
CBD loading arrangements for individual Route 33 services can vary between operators and over time. Passengers should therefore confirm the current boarding point and specifically ask for the 33PM Pipeline via Mombasa Road service.
Do not rely on the number 33 alone because several Route 33 variants operate towards different destinations and corridors.
Route 33PM from Nairobi to Pipeline
The defining journey for Route 33PM is:
Nairobi CBD → Mombasa Road → GM → Imara Daima → Pipeline
After leaving central Nairobi, the service joins the Mombasa Road corridor and travels towards the Embakasi side of the city.
Unlike Pipeline services approaching from Jogoo Road, Route 33PM uses Mombasa Road as its principal approach towards Pipeline.
Major Route 33PM Stops and Areas Served
Mombasa Road
Mombasa Road is the defining corridor for Route 33PM.
This is what separates the service from other Route 33 variants heading towards similar parts of eastern Nairobi.
Passengers travelling along Mombasa Road towards Imara Daima and Pipeline can therefore identify 33PM as one of the relevant route numbers.
General Motors / GM
The General Motors area, commonly called GM, is an important public transport point along Mombasa Road.
It provides connections between Mombasa Road and several residential and industrial areas on the eastern side of Nairobi.
For Route 33PM passengers, GM is an important landmark before the journey continues towards Imara Daima and Pipeline.
Imara Daima
Imara Daima is one of the key areas along the Route 33PM corridor.
The neighbourhood lies close to Mombasa Road and provides an important connection towards Pipeline and other parts of Embakasi.
Passengers whose destination is Imara Daima should tell the conductor their exact stop because the wider area contains several access points and connecting roads.
Pipeline
Pipeline is the principal destination associated with Route 33PM.
Pipeline is one of Nairobi’s densely populated residential neighbourhoods and generates substantial daily commuter demand towards the CBD, Industrial Area and other parts of the city.
Route 33PM provides Pipeline residents with a connection to Nairobi CBD through the Mombasa Road side of the transport network.
Route 33PM and Imara Daima
Imara Daima is particularly important when understanding Route 33PM because it forms part of the connection between Mombasa Road and Pipeline.
The area is also served by other public transport services, so commuters travelling specifically to Pipeline should make sure their vehicle continues beyond Imara Daima.
Passengers whose journey ends at Imara Daima may also have several alternative services available along the Mombasa Road corridor.
Route 33PM vs Route 33PJ
This is one of the most important distinctions for passengers travelling to Pipeline.
Both route numbers are associated with Pipeline, but they use different major corridors.
Route 33PM — Pipeline via Mombasa Road
The M in 33PM helps identify the service associated with the Mombasa Road approach.
Its journey serves the Mombasa Road/Imara Daima side before reaching Pipeline.
Route 33PJ — Pipeline via Jogoo Road
Route 33PJ is associated with Pipeline through the Jogoo Road side of Nairobi’s transport network.
Therefore, passengers should not assume that 33PM and 33PJ follow the same journey simply because both eventually serve Pipeline.
The better route depends on where the passenger is boarding and which corridor is more convenient for the journey.
Route 33PM vs Other Route 33 Services
Route 33 is particularly interesting because Nairobi’s public transport network uses several variations of the number.
Other Route 33 services have historically been associated with destinations including Fedha, Imara Daima, Utawala and other parts of the Embakasi corridor.
For this reason, passengers should read the complete route code and destination board.
For Pipeline through Mombasa Road, look specifically for:
33PM
rather than simply 33.
Does Route 33PM Use Mombasa Road?
Yes.
Mombasa Road is the principal corridor that defines Route 33PM.
The route number itself is commonly documented as Pipeline Mombasa, distinguishing it from the Pipeline service operating through Jogoo Road.
Does Route 33PM Pass Imara Daima?
Yes. Imara Daima forms part of the Route 33PM corridor towards Pipeline.
Passengers travelling specifically to Imara Daima should confirm their intended stop with the conductor.
Route 33PM Return Journey: Pipeline to Nairobi CBD
Route 33PM also serves commuters travelling from Pipeline towards Nairobi CBD.
The return journey connects Pipeline with the Imara Daima/Mombasa Road corridor before continuing towards central Nairobi.
Traffic along Mombasa Road can substantially affect the journey during weekday peak periods.
Passengers should confirm the final CBD drop-off point because city-centre operating arrangements may vary.
Route 33PM Matatu Fare
Route 33PM fares depend on the passenger’s boarding point, destination, time of day, traffic conditions and passenger demand.
A passenger travelling the complete Pipeline–Nairobi CBD journey may pay a different fare from someone travelling only between Imara Daima, GM and another point along Mombasa Road.
Fares may also increase during morning and evening rush hours, rainy weather and periods of unusually high passenger demand.
Important: Nairobi matatu fares are not always fixed and may change at any time. Any fare published in this guide should therefore be treated as an estimate rather than a guaranteed price.
Passengers should confirm the current fare with the conductor before boarding.
Fare last checked: Current Route 33PM fare requires field verification.
Mombasa Road Traffic and Route 33PM
Traffic conditions are an important consideration for Route 33PM passengers.
Because the service relies on the Mombasa Road corridor, congestion around the approaches to the CBD, Industrial Area connections, GM and the wider Embakasi area can affect travel times.
Passengers travelling during morning or evening rush hour should therefore allow additional time for their journey.
