This catagory is only for items that were introduced in 2003.
The coupling style on all the existing engines and rolling stock had now changed from the basic "hook and eye" style to a U-hook. All the engines now received both the hook and eye coupling, which enables you to couple onto another engine. This changed the direction in which the rolling stock with the basic "hook and eye" coupling faced, as the eye couplings were on the opposite side of the engines that they should have been. The age profile also changed, from 3 years to 2 1/2 years.
