Hi,

Could anyone assist me with some informtion on block signals.  I have two NJ International Bi-directional D Type block signals, one being 28 ' high and the other 15' high.

I'm trying to find out under what circumstances they would have been used in relation to their height.  28' seems quite high, not quite signal bridge height but higher than a dual head interlocking signal.

Any assistance appreciated.  Thank you.

 

Regards


Scott

Height

The height of a signal doesn't affect its indication, just depends on physically where its located and how far it needs to be seen.  It might also vary by railroad.  Some railroads might like 20 ft high signals and some 15 ft high signals.
