Imblesbrook Light Railway (ILR)

Description
The Imblesbrook Light Railway (ILR) is a small light-rail/tram network around the Nydalen area, running between Nydalen Bridge station, Hillersbury, Millsbury, and Nydalen & Imblesbrook, as well as an extension to Yardley.

It opened in 1999 using IM4000 trams similar to those used on the Croydon Tramlink (CR4000) for the sake of saving money, instead of creating an all-new design. In late 2008 they were replaced with new Flexity Swift IR-50 vehicles, due to the unsuitability of the CR4000 design for the higher than expected volumes of passengers, especially due to its lack of front couplers for multiple workings in service. This involved extending the platforms and raising them to the height of the higher-floor vehicles. (see Rolling Stock)

The extension to Nydalen Bridge opened in 2001, and the new line to Yardley in 2008.

Service
Most services run the full length of the line between Nydalen Bridge and Imblesbrook. However, terminating bays are provided at Millsbury (towards Imblesbrook only) and Hillersbury (both directions), and some trains terminate there to provide a higher intensity service where it is needed on the line depending on the day.

During peak hours, when many passengers are travelling between Nydalen, Imblesbrook and Hillersbury, 4-car trams generally run. There are two permanently-coupled 4-car sets, which are used exclusively during these times. During other times, only 2-car units are used.

Throughout the day, the frequency of the trains is generally every 10-15 minutes. However, it increases to one every 6-7 minutes during peak hours, when the line is pushed to full capacity. Therefore, the usual pattern is:
 * 6tph from Imblesbrook - Hillersbury
 * 2tph terminate at Hillersbury
 * 4tph continue through to Nydalen Bridge
 * 10tph from Hillersbury - Nydalen Bridge (Shuttle)
 * 6tph from Millsbury - Yardley
