Howdy,

 

This is my first post so please forgive me if I make any mistakes.

 

My little setup is located about 200 yards from a western freight-train
route in and out of the Houston, TX terminals. When I first started out I
thought this massive, biblical-type seismic wave would be my outright
downfall. But, thanks to a lot of help from you guys (see I do read the
mail) I discovered that it was easy to filter out the train - even smack dab
in the middle of a large event. 

 

Over the past 3 years I have gotten pretty good in determining the length,
speed and mass of every freight train that comes by. It presents a beautiful
seismogram of a very close wiggle. Of course no amateur seismologist in
their right mind would want to place a John Cole sensor on horrible Gulf
gumbo and located so close to a train track that teeth can get rattled
loose. But, that's my lot in life so I muddle along.

 

It occurred to me that I can remove the filtering from my helicorder GIF and
everyone can see what these things look like. Just holler if you'd like to
see it.

 

Thanks,

Joe

I would suspect railroad traffic sequenced along a track.  During the night
when other traffic is quiet you may see the railroad from farther distance.
In my location the noise builds and then decays over several minutes.  I
don't see one every hour but there is a daily schedule that shows up and
when the wind is right I hear the whistle to verify.  

 

    Hi Randy,

 

    From this I assume that you still have steam trains with very heavy
engines, in the US? We are mostly electrified with motors in each carriage,
but there are some local Diesel trains. We don't often see train signals,
unless we are very close to a line.

 

    Regards,
