Number Two

This is the most exciting photo taken today, while sitting at traffic lights. Today I give you Railway Bridge Number Two.

I have Googled Streetview on other bridges in the area and cannot see the method in numbering: perhaps it depends on the status of the line; this is not a main line, (their numbers are in the high teens in this area) it runs to the Edinburgh South Suburban line and Millerhill Depot. No doubt other blippers can explain.

Thank you for comments received recently, I've been watching your blips but hope to be back commenting now.
