The CRRC eD12 is a battery-electric double-deck city bus offered by CRRC Electric Vehicle Co., Ltd. (中车电动). In Singapore, a 3-door 2-staircase version of this bus was co-developed by CRRC and ST Engineering, with bodywork construction by Gemilang Coachworks.
The bus was first spotted in Singapore in October 2024. Delivered in a Lush Green livery, this bus was exhibited at SITCE 2024, and could be a demonstrator unit to be offered to the Land Transport Authority (LTA) for revenue service trials.
In line with LTA’s ongoing efforts to rapidly electrify the public bus fleet, half of all public buses will be electric by 2030. Detailed coverage of this rollout can be found at Electric Buses in Singapore.
Manufacturer Background
CRRC Electric is an electric bus manufacturer in China, best known for its association with the CRRC conglomerate that builds rail vehicles. Between Jan–Aug 2023, it was the sixth-largest manufacturer in the Chinese new energy bus market by sales volume, with 1,519 buses sold. Apart from selling whole buses, CRRC Electric also sells electric drives and control electronics for electric buses, marketed as “T power”（T动力）.
Outside of its domestic market, CRRC Electric has seen volume orders in New Zealand, Sauri Arabia and South Korea, with limited trials of its buses in France, Hungary, Belarus and Malaysia.
Double-deck buses
CRRC previously supplied electric 2-axle double-deck chassis to New Zealand. In 2018, an initial fleet of 10 electric buses was launched, followed by 31 more from 2021. All these buses were built by local coachbuilder Kiwi Bus Builders and began service in Wellington.
In March 2024, a prototype three-axle double-deck (CRRC eD12 MAX) entered passenger service in Auckland, bodied by Gemilang Coachworks. In October 2024, Tranzit Group unveiled a similar Gemilang-bodied CRRC eD12 MAX as part of a fleet of 26 units acquired for service in Waikato and Auckland. These buses are equipped with 508 kWh CATL batteries and have a capacity of 80 seated and 20 standing passengers.
SITCE 2024
A CRRC eD12 bus intended for the Singapore market was showcased at the LTA-UITP Singapore International Transport Congress & Exhibition (SITCE) in November 2024.
The display model at SITCE 2024 featured a Lush Green vinyl wrap promoting AGIL Drivesafe+, an Advanced Driver Assistance System by ST Engineering. For exhibition purposes, the upper deck was modified to include tables and seating that faced each other.

Layout
The CRRC eD12 is a full-low-floor double-deck bus with three doors and two staircases. The full-low-floor layout is ideal for passenger movement, as the rear staircase leads directly to the third door, which encourages upper-deck passengers to exit from the rear door.
LTA’s preference for three-door buses is evidenced by LTA’s previous 100 double-deck bus order in 2019, which mandated a three-door two-staircase layout, with the rearmost exit door situated behind the rear axle. More recently, the 360 single-deck electric bus order in 2023 also required a three-door layout.
The bus has a capacity for up to 120 passengers; 63 seated and 57 standing.
Lower Deck
The lower deck of the bus includes 12 seats, 2 wheelchair bays (each with a foldable seat) and licensed standing space for up to 57 passengers. The design features a fully low-floor aisle from the entrance to the rear third door, enhancing accessibility.
Passenger seats are supplied by Kiel (model: Kiel Citos) and come upholstered in grey-blue or maroon seat covers. Stanchion poles are turquoise, a colour scheme similar to that of Volvo B5LH buses, with bell attachment areas coated in yellow to aid with visual identification.
Staircases
The bus is equipped with 2 staircases: the front staircase is located behind the driver’s cab, and the second is positioned at the rear, providing direct access to the third door.
This layout allows passengers to quickly exit from the upper deck, making alighting more convenient and efficient. Most passengers on the lower deck typically exit through the middle door.
Upper Deck
The upper deck seats 51 passengers. For the SITCE 2024 exhibition, a temporary seating arrangement was configured with rear-facing seats and tables to facilitate trade show discussions.
Driver Cabin
The driver’s cabin is outfitted with the AGIL DriveSafe+ Advanced Driver Assistance System (ADAS), which includes forward and side blind spot monitoring, collision detection, and lane departure warnings. An Anti-Fatigue System is also included.
Additionally, the bus uses a camera-based mirror system instead of traditional wing mirrors. Two vertical CCTV monitors replicate the view of wing mirrors, while a third overhead monitor provides an overhead view of the front and front-left blind spots.

Can add more 100% Electric buses?? Why are there still so many scania k230ub in sg?? Then still add 2 more year lifespan? Oh my god.
Not enough buses for now especially with BCEP. Hence K230UBs stay back to support expansion.
The effectiveness of 3D2S double deckers cannot be compared with bendy buses… Solid fact.
Yeah man,Was hoping LTA consider at least 70 units to supplement Airport and short distance feeder service.
Don’t understand why Gemilang love to place the third door nearer to the third axles stripe leaving only a finger gap just like the A95 3-doors.
I think for this bus its because of the battery thats right next to the 3rd door so if they move it more back the 3rd door would be smaller. And for the man a95 3 door, the door must be closer to the 3rd wheel due to the slope of the overhang (even though its this sloped the overhang always almost scrape the road in a bump
Singapore is like the only city outside China that is mass purchasing electric buses and mass deploying them on public bus routes so far.
And probably the only city in the world that will be mass purchasing electric double decker buses and mass deploying them on public bus routes so far.
Do correct me if I am wrong.
london and paris are doing it as well
Another social credit bus.
