They have a triangle pattern of three lunar white lights. The indications given are two lights one above the other points are normal two lights at an angle aprox 45 degrees points reverse Lights out STOP!!! the points are not right It should be noted a point indicator is not a signal. regards John
QUOTE: Originally posted by John Busby Hi all Beware of sweeping statements like most red signals are permisive they most certanly are not. it all depends on which system is being used there are two systems permisive block and Absaloute block

QUOTE: Also, US signals display speed information, rather then route information. Although, you can normally tell the how route is lined from the speed indication.

QUOTE: Originally posted by dehusman The absolute block system or staff system is very rare in the US since the early 1900's. Our signal systems are very much different. The only time anything close to an absolute block system is used is in non-signaled territory when cabooses are not being used or when a cab signal system on an engine fails. If you are modeling the US, then signal systems outside the US won't be very close at all to US systems. Dave H.
QUOTE: Originally posted by John Busby All railways in the EX colonies and protectorates of the United kingdom and a fair few of the European railways use absolute block. NSW acording to the S&C practices and princaples book I got from the S&C NSW office states absolute block working is what is used but that may have changed.
