Electrolysis/Anodes

[rawidman]

A friend of mine told me yesterday than another friend of ours was thinking of moving his boat from our marina to a different one several miles down river. Part of the reason is, his diver told him that the reason boats in our marina went through anodes so quickly (it hasn't been a problem for me) is that electricity from the railroad bridge a mile up river was getting into the water and the fast current was bringing it to the marina.

I couldn't help responding that that was by far the dumbest thing I had heard all day.

To start with, it's not an electric train, they are all diesel. Second, there are private (community) marinas directly on both sides of the bridge. If we had a problem a mile a way, anodes wouldn't last a week next to the bridge. Third, electricity would not be affected by the tidal current (as opposed to electrical current) of water.

I guess when people pay you to do something, they will believe whatever you tell them if you're convincing enough.

Although it has nothing at all to do with your problem I want to point out that all trains are electric. The diesel merely runs generators which power electric motors which drive the train.

I am old enough to remember when they weren't all electric.

Electricity takes the path of least resistance.
I think it would go to ground before it went a mile up/down the river.
Unless the river is deeper than 1 mile.
It would more than likely go straight down the legs of the bridge to ground.
And I don't think the train company would like knowing that their trains were
putting out electricity from the engine to the tracks. That wouldn't be too
good for the yard hands who grab on to the trains to hook and unhook them.

That's my point. The guy who told my friend this seems to be an idiot, yet because he makes his living cleaning boat bottoms and replacing anodes, people believe him.
