The CRRC TEG6125BEV03 is a fully electric, low-floor single-deck city bus model offered by Chinese manufacturer CRRC Electric Vehicle Co., Ltd. (中车电动), better known simply as CRRC. The bus also goes by the model name CRRC C12 and has been dubbed “San Bus King“.

One unit is registered with Go-Ahead Singapore, bearing the registration number SG4006X. Revenue service commenced on 10 December 2021, where it is deployed to Go-Ahead Bus Service 3 on a regular basis. Like the Linkker LM312 buses that entered service in August 2021, the CRRC bus is bodied by Gemilang Coachworks, featuring three passenger doors and a full-low-floor passenger cabin.


CRRC Electric is an electric bus manufacturer in China, best known for its association with the CRRC conglomerate that develops rail vehicles and associated electrical components. In 2020, the company delivered around 5,500 new energy buses domestically, earning it third place in China’s new energy bus market by sales volume (behind Yutong and BYD). 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.

As for the wider electric bus market in Singapore, the Land Transport Authority (LTA) last procured 60 electric buses in 2018, and with no new orders since, this bus is thus believed to be offered to LTA as a trial.

Trial Bus

The Land Transport Authority (LTA) procured 60 electric buses in 2018. With no new electric bus orders since, the CRRC TEG6125BEV03 bus, along with the recently spotted BYD K9RC bus, are both believed to be offered to LTA as a trial, similar to that of the 3-Door MAN Lion’s City SD (SG4002G) in 2017, and the Mercedes-Benz Citaro hybrid (SG4004B) in 2020.

The CRRC TEG6125BEV03 bus is registered as SG4006X and bears the chassis number LHWCK97D3L1209942. The registration number (SG400x) follows in a series of trial buses for LTA.

The bus is operated by Go-Ahead Singapore based at Loyang Bus Depot and recharged at existing 90kW DC electric bus chargers supplied by NARI, which are currently used by Yutong E12 & Yutong E12DD buses. Revenue service commenced on 10 December 2021, with the bus deployed on Bus Service 3.

Back in 2017, Go-Ahead Singapore also trialled a BYD K9 electric bus.

The CRRC TEG6125BEV03 has previously seen operation in Mogilev (Belarus), where two left-hand-drive units were gifted from the Hunan province.


On 20 April 2021, a LinkedIn post by WCA Projects shared that one of its logistics partners, MS Global Freight Solution Sdn Bhd, recently moved an electric bus from Port Klang (Malaysia) to Shanghai (China).

Photos on the LinkedIn post feature the CRRC TEG6125BEV03 bus bearing the Land Transport Authority (LTA)’s Lush Green livery and SG Bus Decals.

The post describes the logistic challenges of moving the bus. Although buses are typically driven onto roll-on/roll-off (RORO) ships, this bus was not drivable and had to be transported on a roll trailer. The bus’ weight and heavy-duty batteries also resulted in additional time for the vessel operator to confirm cargo acceptance.

Similar to the BYD D9RC electric double-deck bus spotted in April 2021, this bus was also built by Gemilang Coachworks to the latest LTA specifications, which specifies Passenger Information Display System as a requirement for all new buses. This is the second electric single-deck public bus model to feature 3-doors for Singapore, with the first being the Linkker LM312 bus.

This bus was also featured in a false-colour image on Gemilang’s website, captioned ‘Aluminium City Bus’ and without SG Bus decals. The blue livery appearance is a frequent attempt by Gemilang to omit LTA’s distinctive Lush Green livery from its promotional material. The manufacturer of the bus was also not disclosed by Gemilang.

Gemilang had also previously built an electric bus based on a CRRC drivetrain. The CRRC CSR6105GLEV1-1 was an electric single-deck bus that was initially trialled in Kuching (Malaysia), then later participated in Johor’s IMBRT Pilot Testing Programme in 2021. Separately, CRRC and Ikarus produced a prototype three-door single-deck electric bus called the CityPioneer (commercial name IC 1211 U) in 2018, incorporating CRRC electric drivetrain technologies.

In 2018 and 2019, a CRRC C12 bus was exhibited at various trade shows, in a left-hand-drive, full-low-floor configuration with three passenger doors.

Should the right-hand-drive version of this bus be a completely new product, the shipment of the bus to China might be required for homologation, testing, final quality checks prior to delivery, or possibly for public exhibition purposes



The CRRC C12 is a low-floor single deck bus, offering step-free access across the entire length of the bus.

It features a three-door configuration, with an entrance door at the front, an exit door in the middle, and a second exit door at the very rear of the bus.

The bus features 28 seats, 2 wheelchair bays and licensed standing space for 61 passengers.

3 Doors

Bus Captain Cabin
Wheelchair Bay & Ramp

The bus features two wheelchair bays, both located opposite the exit door. They each accommodate one passenger-in-wheelchair (PIW), and are equipped with USB charging ports. Foldable armrests and a stroller restraint system is provided for wheelchair users and the securing of prams respectively.

Passenger Information Display System

The bus is installed with a Passenger Information Display System from LECIP, which features an interior coloured LED panel and a LCD panel.

Other Features

The air-condition outlets can be manually closed or open by commuters. The bus is also equipped with USB Charging Ports which are located on the side interior panels.
