SMB92U on Service 970

Overview

The Mercedes-Benz OC 500 LE is a modular, heavy-duty, twin-axle bus chassis produced by Mercedes-Benz/EvoBus Ibérica, Spain. It was designed as a modular platform for low-entry city, suburban, and intercity buses with a maximum gross vehicle weight of 19.1 tonnes. The main modules consist of: 1) driver's pedestal, 2) front axle, 3) buggy centre section, 4) drive axle and 5) engine. It has much in common with the chassis used for the Mercedes-Benz Citaro integral bus range, and also the raised floor OC 500 RF coach chassis. The engine is horizontally mounted over the rear overhang.

SMRT Buses

Demonstrator

In 2008, SMRT received a demonstrator OC500LE unit bodied by Gemilang Coachwork for evaluation. It is the first wheelchair accessible single-deck bus to be operated by SMRT, and was also the first bus to be registered under the new "SMB" prefix.

Batch 1

Later in 2008, SMRT made their first purchase of 66 OC500LEs. It was SMRT's ever first purchase since the re-branding. This batch of buses was similar in specifications to the demonstrator, but featured a larger sized side and rear Electronic Destination Signage (EDS).

As part of a trial, SMB11D to SMB18K were installed with an Elekon Micro Systems display beside the entrance, showing next bus arrival details. However, the trial has ended and these displays are no longer in use, and currently only displays "Welcome Aboard" messages in both English and Chinese.

Batch 2

SMRT made a further purchase of 67 OC500LEs in 2009, with the same specifications as the 1st batch of buses. The interior featured an updated colour scheme for the seat covers. A rear tire inflation system was also installed on the rear axle, but was later removed.

SMB76S had its original rear EDS unit replaced with a smaller one, similar to the demonstrator, while SMB91Y had its entire EDS set replaced with a Mobitec set after an accident.
