Eventually they will run out of parts and supplies and Siemens has been lately notorious for discontinuing them early than the industry is accustomed to. That's why in Japan railway companies are changing their VVVF inverters to Toshiba or Mitsubishi made ones.The case of the L is pretty bad. As it was a test bed project, no one else in the world uses the same system. It was also one of the first RF based CBTC implemented. It may become more costly to order both the on-train and way side equipment to the point that it will become cheaper to change to an unified system. Paris will switch from induction based to RF based soon and it's supposed to have the improvements made after the L line tests. |
