These three are being sold for parts only non-working condition. Normal retail these Siemens Etu are very expensive. I think that each of them probably need some small repair. They were pulled out of operation due to some type fail failure.
However, I know that none of them have been extensively used. I m actually not sure the status on all three of them, but I do want to mislead anyone believe that these are in great shape.
