Hi All This is just a quick question, with (hopefully) a simple answer, but would anyone be able to tell me what the frequency of a flashing yellow aspect is, and also if you happen to know what the flashing green aspect frequency was on the Peterbrough (I think) lines for higher than 125MPH running. This is just to help me with a model railway project to create the software for a signal capable of this.

According to this document at RGS online: Quote: 2.2.1.4 Colour light signal lights that are designed to flash shall comply with the following "Don't stress/ relax/ let life roll off your backs./ Except for death and paying taxes/ everything in life.../ is only for now."

Filament signals often take time to fade to black so they can appear to be on longer than the figures Steamer posted.

In SSI areas, the signal module maintains a current to the lamp at all times and the full current is passed to the lamp via a resistor from outputs 0 and 1 (depending on whether it is a single/double yellow aspect. Hopefully the diagram below can explain it slightly better! (Image from IRSE Red Book) Log in to reply |

The same happens in RRI areas as well. I do have a diagram but cannot remember where.
