Singapore Buses route 174e

Service 174e is an Express variant of Service 174, plying between Boon Lay and Kampong Bahru. It passes through Boon Lay Avenue, Bukit Batok, Tanglin, Orchard, Dhoby Ghaut, Clarke Quay, Chin Swee Road and Outram Road.

Service 174e was introduced as a Fast-Forward variant of Service 174. The service benefits residents of Jurong West and Bukit Batok to get to their workplace more quickly than its parent route during the peak hours. It also charges express fares.

The route skips selected stops throughout its route in both directions. Its express sector between Jalan Jurong Kechil and Napier Road is highly flexible, with buses able to ply the PIE, Dunearn/Bukit Timah Road or Holland Road. The Holland Road option is preferred during school vacation periods when Clementi Road has substantially less traffic.

On 23 March 2006, Volvo Olympians were replaced by Dennis Trident 2/Plaxton Presidents.

On 7 April 2012, the service was retained by First Western, with Alexander Dennis Enviro400s and Wright Eclipse Gemini bodied Volvo B7TLs introduced.

On 22 June 2013, the route was included in the sale of First Western's Soon Lee garage to Metroline. The route will be retained by Metroline with brand new MCV EvoSeti bodied Volvo B5LHs from 6 April 2019.
