Clearly nothing is drop into place plug and play, but there is definitely a standard for Light Metros that has become normalized and thats standard US rail gauge, 1500v DC overhead panto, with the IEEE 1474 standard for train control communications. Stick to that and it will be a lot easier for other manufacturers to bid on future work.
Of all the train systems out there, the concept of "light metro" seems the least standard and most vague. At least that's been my takeaway. The concept is open to interpretation, companies selling all kinds of *solutions* for your city's rapid transit ails. I love the concept of a intermediary capacity subway line, but 'definitely a standard' for light metro?
