Dublin bus is replacing the 61 transferred buses with new SG386-446 Dublin bus has 100 other new buses in 2018-19, SG 371-385 for expansion (Dublin is booming unlike London) and SG447-531 for routine replacement
SG are Volvo B5TL (euroVI) Wrightbus Gemini3 (from 2014-2019) still being delivered GT are Volvo B9TL (euroV) Wrightbus Gemini2 (from 2012-2013) 160 in fleet
Dublin bus also has 70 Volvo B9TL Enviro 500 VT class from 2004-2007 97 Volvo B9TL Enviro 400 EV class from 2007-2009 50 Volvo B9TL Gemini VG class from 2007-2009 192 (being replaced) Volvo B7 ALX400 ALX400 from 2006 (most of the last ALX400 built before enviro400 replaced them), there were an older batch of these designated AV class, but not sure if any left as the SGs replace them
The Celtic tiger saw big bus expansion 2006-2008, the orders were stopped after financial crash, but are now booming again, which explains the uneven age profile. There are few hybrids due soon for evaluation
A complete network redesign for Dublin's bus services is on the cards.
Recently announced, the proposed new network will see every bus route in Dublin changing. Services will be concentrated on seven core high-frequency spines, which will be lettered from A to G. Numbers would differentiate different branches of the spine (e.g. A1, A2 etc.) Long, slow and infrequent routes from outer suburban areas will be replaced by more frequent feeder services into either the the core network, or in some cases the LUAS tram. The proposal is complemented by a high-frequency orbital route in the suburbs - currently orbital services are very limited, with many passengers needing to travel into the city centre and out again to access a neighbouring area. Again this will link up with the core radial routes.
The proposed new network is currently out to public consultation. It is hoped to implement the new network in late 2019.
