The main train of thought at Angel Trains is leasing rolling stock. Angel Trains owns and leases more than 4,400 rail vehicles in the UK to rail network operators. It finances construction for new railway stock, as well as the rebuilding of older stock. The company leases to 18 of the 19 train operating companies in the UK, including Arriva and Virgin Trains. In 2008 a consortium of private insurance and pension fund investors acquired the company from The Royal Bank of Scotland Group, which in turn sold it to partners at Babcock & Brown for �3.6 billion. Angel Trains reverted to a consortium that includes Arcus Infrastructure Partners in 2008 after Babcock & Brown's demise.
