Passenger Trains > A Different Kind Of Position Light Signal & Where Is ItDate: 07/20/14 11:46 A Different Kind Of Position Light Signal & Where Is It Author: Out_Of_Service Date: 07/20/14 12:06 Re: A Different Kind Of Position Light Signal & Where I Author: SCAX3401 While I don't know where you particular photos were taken, the Los Angeles Metro light rail lines use these white "position light signal" or "digital semaphore" to govern train operations while on street trackage. I imagine other light rail lines use the same system.

------------------------------------------------------- > I've seen signals like that in Baltimore, too. Yes, they are on the Howard Street "street running" section of the light rail line. It starts at about the old B & O Mt. Royal Station and ends at Pratt Street near Camden Yards. However, those photos were not taken in Baltimore, MD.

We'll have to wait for the author to confirm.

Date: 07/20/14 14:34 Re: A Different Kind Of Position Light Signal & Where I Author: Out_Of_Service this will answer your questions ... i followed the Tooterville Trolley from Cooper St to Riverside Dr formerly Delaware Ave where P-RSL street trackage, to Cooper's Point yard, on cobblestone lay to switch the very important consignees of Campbell Soup and RCA among a few smaller other ones ... there's a signal in every photo sans 1
Photo #1 heading west on Cooper St Photo #2 turning south onto Riverside Dr Photo #3 making the stop for the Camden Aquarium heading for the end of the line at the Susquehanna Bank Center ... the station at the end of the line is in the area where the old P-RSL roundhouse once stood Edited 1 time(s).

My guess would be vertical - go, horizontal - stop, diagonal - slow. Correct? Date: 07/20/14 18:27 Re: A Different Kind Of Position Light Signal & Where I Author: Out_Of_Service Cumbresfan Wrote:

Correct? it's hooked up to the street light signal to avoid conflict between vehicles and the LRVs ... when the street signal is green the River Line signal is in the horizontal stop position and vice versa with the diagonal on the yellow but unlike a street light signal that goes green yellow red ... these signals horizontal-diagonal-vertical then they go from vertical-DIAGONAL-horizontal Date: 07/21/14 14:07 Re: A Different Kind Of Position Light Signal & Where I Author: Cumbresfan Out_Of_Service Wrote:
