so... austria has an engine making this sound while starting off:

seems as if its due to the power regulators.

That's cool. Is this a typical hybrid locomotive?

hybrid? between what?

its purely electric.

it probably might be able to cope with the different AC-frequencies, like 15 2/3 Hz in .de and probably 50 Hz in other european countries like .fr if you like to call that hybrid...

since its using wave cutting to control the amount of energy the engines get; thats what makes them howl that melody...

Does anyone here know anything about infrared motion detectors?  As in, do they wear out?  I just got back from another false alarm.  I can't find anything that would have set them off yet again.

most probably the lenses can become pale / dirty?

maybe you've got a cat hanging about? ;-)

No cats around here..I'd start sneezing if there were.  As for the dirty lens...that should make the sensor less sensitive.  I am wondering about transient voltage spikes or breakdown of the semi-conductors in the sensor.

 

Trust me, there is nothing more fun than getting up in the middle of the night to investigate an alarm at a remote location.

The cable company 'fixes' their routers overnight so if you have a voip phone that you're running your alarm service over, it will appear to be cut every once in a while.
this happens all the time over here, though I'm sure that's not what you're talking about.

Like a hybrid automobile. The typical design for a "diesel" locomotive is actually a diesel generator plus a bunch of electric motors, one on each wheel.

ah. these are rather unusual in germany / europe. most tracks have overhead contact lines. just some rather rural lanes or where there are tunnels with not enough space are operated with these diesel electric trains:

http://www.google.com/images?q=talent+db&hl=de&client=iceweasel-a&rls=org.mozilla:en-US:unofficial&prmd=ivns&source=lnms&tbs=isch:1&ei=zapATaz0B4aKlweQ5OWoAw&sa=X&oi=mode_link&ct=mode&cd=2&ved=0CA4Q_AUoAQ&biw=1020&bih=471

they replaced systems with heavy pure diesel engines with big torque converters (better hold your ears when they start off next to you...) in the late 90'ies.

btw, there are even diesel ones with direct shifting transmissions in the trains on the pictures above...

so... since current frequency, ac/dc, or the legal issues which color the needle of the tachometer or its background has to have in .de/.fr/.at its rather usual to call these hybrid if they may pass the border legally plus are still operational with the current...

so... it might happen that the rider has to switch the display over to .at mode when he passes the border, though the operator is still the same ;-)

this is that pure diesel with the torque converter:

http://de.wikipedia.org/wiki/DB-Baureihe_218

it was most common in .de in the 80'ies, is replaced by the lighter 'talent's on that google images link...

the 218 was known for destructing the tracks to quick because of its weight...

heh, for the weight of the 218 (80t) (without trailers) you get a whole talent: http://de.wikipedia.org/wiki/Siemens_Desiro_Classic (69t) and two times 300 kw in comparison to 1800 kw...

Today you also see them carying castor trailers with nuke-garbage...

Does the room get any outside light? if so the IR filter on the detector might be fading making it trigger on other wavelengths.

Our commuter railroads have either overhead power lines or a third rail. We use diesel for long distance rail, especially freight rail. Remember, we have much longer distances.

Yes, lots of light in the morning.  More likely, it's the overhead radiant heater.  The room is an entryway at the store where I work.  I think the radiant heater is creating a hot spot on the metal in the room.  When it's cold enough, it interpets the hot spot as motion....I think.  Nobody agrees with me, but they have no better answer.

yea I know; since distances are shorter over here, there is less space so there isn't much dedicated freigt-rail in europe.

I guess the new highspeeed lanes are the first ones to make this distinction, next to the commuter rail systems in berlin that also have the 3rd rail power system..

unless you need to have something failsafe like the castor transport there is no need to have diesel freight lines...

most lines that have frequent traffic have overhead lines, so most freight railtraffic is also done with electric engines.

whew. now this is a bad thing. coincidence?

yesterday late nite such a talend alike train collided with a freight train.

http://www.spiegel.de/fotostrecke/fotostrecke-64094.html

this is the freight engine:

http://www.spiegel.de/img/0,1020,3560261,00.jpg

its even older than the 218 pictures i've posted before.
