F125 in the Darkness with Florescent Light Coming OUT of it (w/ Photos)
Posted by K. P. Harrier on Friday, October 20, 2017 8:07 PM

A new F125 was seen this morning (Friday, October 20, 2017) before sun up, with the large screened COMPARTMENT behind the prime mover all lit up!

Was that lit up a fluke or a new standard?

From the above scene in San Bernardino, CA, the two-unit power will push-pull push the Metrolink all the way to Los Angeles on the San Bernardino Line which is about 57 miles to Union Station.

Look at the advantages of the light.

Might prevent some idiot from running into side of loco or trailing train cars ?

Enables better walk arounds of locos ?

For our rail viewing fans at night it will light up the adjaecent ROW.  

Help for loading baggage at night.

Engineer(s) better vision at night when walking off platforms.

Cannot let chargers out do them ?  Anyone know  which has more light ?

Other?

A source confirms the F125’s run with the behind the engine area compartment lights ON.

The florescent-like look of those lights undoubtedly is from a mild bluish Light Emitting Diodes (LED) lighting

The headlight, ditch lights, and front number boards have that mild bluish look in contrast to the historic incandescent white-yellow.

The above view is from a highly cropped digital photo.

The PRIIA 305 specification requires LED or fluorescent lights for the engine room.

Required is a 30 second off delay following the last detected movement of personnel. So it seems a railroad decision to leave the engine room lights burning.

   This is something that has concerned me since cars went from sealed-beam to halogen headlights, and now, LED.   Remember yellow fog lights?   The longer wavelength yellowish light is better at penetrating fog or mist, since the shorter wavelengths are scattered more by the droplets in the fog.   The bluish light appears brighter, but I wonder if it may actually be a disadvantage.

   My mind's made up.   Don't confuse me with the facts.

I agree, those headlights on the F125's don't look very bright during the day, but might be easier to see at night. 

I wonder what the engineers are saying about these new hi tec locomotives.

I could have used such lights 48 years ago when I walked back to my coach, going through two E8 engine rooms on the way. The flagman had accompanied to the cab of the lead engine, and then he went back, carrying his flashlight with him.Smile

The LED headlights the new amtrak electric motors have are pretty bright, day or night.
