Re: Vendor lock in by rolling stock manufactures

A camshaft controller can’t do this, can be repaired or reproduced by any competent workshop, and isn’t subject to planned obsolescence by the unavailability of proprietary electronic components.

If this is progress it is bullshit. Just because something can be done doesn’t mean it should be.

As usual, the only cohort to benefit fro this will be the lawyers.

It's quite common for tram, bus and train operators to contract out maintenance to companies other than the original manufacturer. Perhaps in this case the operator was breaching an existing contract during warranty period, for example?
