Old Dalby Test Track to be used by Metronet

The stock is being built by Bombardier in Derby, so by using Old Dalby it can be commissioned whilst on delivery. Aylesbury to Claydon is also not electrified at all. While Old Dalby is currently (excuse the pun) NR 25 kV AC and Movias need LU 660 VDC, the grid feeder substation and switching gear will already be in place, along with linseside fencing to latest standards and so on. Its rather simpler to convert an already existing electrification from one to another sytem even if they are very different. -- Nick -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |
