In April 2007, First introduced the 598L, which was introduced when First replaced its 593 daytime service with a new Overground route, the 598. However, while the 593 ran via Castle Hill and Belle Green, the 598 runs direct between Hindley Green and Wigan. Castle Hill was still served by the 540, whose frequency increased from every 30 minutes to every 10 minutes and the 32 was re-routed to serve Castle Hill, the 598L was withdrawn in 2009 and replaced by rerouted 598 buses directly serving the Estate.
