(Siemens Image via Amtrak) DETROIT and NEW YORK - Amtrak is looking to replace 83 aging passenger trains — some of which are half a century old — with much more modern equipment starting in 2024. The price tag: $7.3 billion, which still needs to be fully approved by Congress. Amtrak said Wednesday that under the contract with German manufacturer Siemens AG, some of the trains will be hybrids, able to operate on diesel fuel and electricity where wires are available. The new trains will replace Amfleet, Metroliner and state-owned equipment.
