Yutong ZK6125BEVGS (E12DD)

Continued from Page 1

Interior

The Yutong E12DD is a full-low-floor bus, offering step-free access from entry/exit doors until the last row of seats. Buses are configured with two doors: an entrance door at the front, and an exit door in the middle, typical for double-deck buses in Singapore.

Interior coverage will be outlined over the following sections:

  • Lower Deck
  • Staircase
  • Upper Deck
  • Additional Features

Lower Deck

The lower deck of the bus is noticeably less spacious as compared to other double-deck buses as three rows of seats are eliminated to accommodate rear-mounted battery packs and powertrain components. The last row of seats on the lower deck are typically located behind the rear axle, but on the Yutong E12DD, the last row is located in between the drive and tag axle.

Seats were supplied by Polish company Ster (Model: New City) in Blue seat covers, with priority seats in Red.

There are 13 permanent seats on the lower deck. A staircase behind the driver’s cab connects the lower and upper decks. Mood lighting in the bus cabin is offered in 3 colours—Dark Blue, Sky Blue and Orange, and are manually toggled by the Bus Captain.

Priority seats, which are indicated in red seat covers, occupy the first row behind the exit door on the lower deck. The red colour theme extends to the wheelchair backrests.

The rear section of the bus sits five abreast in forward-facing seats. In place of rear-facing seats above the wheel well, two metal storage racks are provided for the benefit of commuters with bags or groceries.

Grab poles and handgrips are located on both sides of the aisle. All seats also have hand grips to provide commuters with additional support.

Yellow bus stopping bell-pushes are located around the bus cabin, mounted to stanchion poles. Some stanchion poles have areas around the bell also coated in yellow to aid with visual identification. Emergency hammers are located on pillars in-between windows.

Like most double-deck buses in Singapore, the Yutong E12DD buses are configured with two doors: an entrance door at the front, and an exit door in the middle. The entrance doors are conventional inward-swinging leaf doors, while the exit doors are outward-swinging plug doors. They are supplied by SMC Transit.

The entrance door is no longer fitted with a centre pole as per older buses for the benefit of stroller boarding. Signs indicating no standing on the door movement area are printed on the floor.

The bus features two wheelchair bays: one behind the front left wheel well (“front”), and the other located opposite the exit door (“rear”). They each accommodate one passenger-in-wheelchair (PIW), and are also equipped with USB charging ports, a foldable seat and a stowable armrest. A stroller restraint system is installed at the forward wheelchair bay.


Staircase

The staircase allows for passenger movement between the lower and upper decks of the bus. A seat counter (LED seven-segment display) on the lower deck displays the number of available seats on the upper deck. The staircase is designed with two flat staircase landings (“straight staircase”). A poster frame is also placed in the staircase area for commuter notices.


Upper Deck

The upper deck of the bus seats 55 passengers. Seats are arranged in conventional four-abreast, with a central aisle running the length of the bus.

Grab poles run the length of the aisle for commuters moving around the bus. All seats also have hand grips to provide commuters with additional support.

Bus stopping bell-pushes are located around the bus cabin mounted to stanchion poles. Emergency hammers are located on pillars in-between windows.

Two rear-facing seats are located on the upper deck, above the staircase. The rear section of the upper deck is also slightly raised to accommodate the electric air-conditioning system and batteries, hence the single step at the rear.

Unique to the Yutong E12DD are rear-facing seats located next to the staircase. These maximize the capacity of the upper deck by protruding into otherwise-empty space above the stairwell.


Drivers’ Compartment

Yutong E12DD buses are fitted with the ACTIA Podium 2 dashboard.

In place of analogue dials, the Yutong E12DD dashboard features a digital display screen in the centre, displaying the speedometer, throttle, state-of-charge, and air pressure among other parameters. Notably, the dashboard graphics depict a two-axle Yutong E10DD in Lush Green.

Mounted around the dashboard are the various fare collection equipment as well as the Trapeze Common Fleet Management System (CFMS) driver display unit.

A CCTV monitor, located above the driver, assists with monitoring of the surroundings. The Electronic Display Sign (EDS) controllers are co-located with the CCTV monitor above the driver.

The Yutong E12DD buses come equipped with the Golden Eye Driver Anti-Fatigue System, supplied by TNT Surveillance. The camera monitoring unit is installed on the top of the dashboard.

Collision Warning System

A Collision Warning System is offered by TNT Surveillance. The front collision warning camera (Front Alert Camera T-FA) integrates Forward Collision Warning, Lane Departure Warning, Distance Monitoring and Pedestrian Detection features. The side collision warning camera (Side Alert Camera T-SA) detects pedestrians or cyclists in the blind spot on both sides of the vehicle.

Both camera systems are each connected to three identical display units mounted on the dashboard console, which issue visual and audio alerts in real-time. The Side cameras are connected to the left- and right-side display unit, while the Front camera is connected to the centre display unit.


Features in-depth:

Wheelchair Bay

Wheelchair accessibility is offered via a manual wheelchair ramp installed at the rear door. LTA specifications call for two wheelchair bays on new buses in line with providing for an ageing population. They also offer more standing space, as well as room for unfolded prams.

Both wheelchair bays are located opposite the exit door. Each bay accommodates one passenger-in-wheelchair (PIW), and the wheelchair backrest contains a foldable seat that doubles as a rear-facing seat. These seats do not contribute to the licensed seating capacity of the bus.

The forward wheelchair bay is also equipped with a stroller restraint system. USB Charging ports are also provided at both bays.

A unique feature of these buses is the pivoting handlebar at each wheelchair bay, for the benefit of PIWs. It can be manually deployed and stowed depending on the needs of the passenger. The handlebar on the Yutong E12 is shown below — the Yutong E12DD works the same way.

Handlebars are deployed by lifting the bar, rotating it 90 degrees or 180 degrees towards the aisle, then dropping it in place. At full reach (180 degrees), the design allows for PIWs to easily manoeuvre in and out of the wheelchair bay.

Passenger Information Display System (PIDS)

The Yutong E12DD buses are equipped with Passenger Information Display Systems (PIDS) for commuters. All display units are supplied by Japan-based company LECIP.

  1. LCD Display Panel (21.5″) (x2) — Lower & Upper Deck
    Shows the bus service number, destination, current time, next bus stop, and up to 3 subsequent bus stops, along with rail connections at these bus stops.
  2. LCD Display Panel (21.5″) — Exterior-facing, beside entrance door
    Shows next few MRT/LRT stations served, and number of bus stops to that MRT/LRT station
  3. LED Colour Display (x2) — Lower & Upper Deck
    Shows the bus service number, destination, and next bus stop
USB Charging Ports

The bus is equipped with USB charging ports for all seats on the side panels of the bus. Each charging port has room for two USB cables, rated 5V, 2.1A. A spring-loaded dust cover protects the USB ports when not in use.

Automatic Passenger Counter System

Automatic passenger counters by TNT Surveillance (Model: T-APC) is installed above the front and rear doors, as well as above the staircase on the upper deck. This feature enables the gathering of more accurate passenger loading data, as well as displaying the number of available upper deck seats.

    This bus model looks just like the original double decker bus model in Singapore. The same box design. It may feel like a return to heritage. But I feel that we really missed the opportunity to have a more recent design.

    Similar to the Yutong E12, for the Yutong E12DD electric buses under SMRT, they will park at Bulim Bus Depot.
