Seems fine to me. Thanks for the neat trip report.

Yes. My geekiness is not constrained to electronics.

I assume they used the telegraph to synchronize local clocks. How well did
that work? What sort of tricks/techniques did they use?
The wiki page says 30 seconds a week for railroad pocket watches.
How long could the local clocks coast if the telegraph was out? Does anybody
know anything about the overall error budget?
These are my opinions, not necessarily my employer's. I hate spam.
