We spend a a great amount of or energy and film photographing trains. But without the infrastructure and the people the trains would go nowhere.

I am going to start off the infrastructure thread with this photo of a groundthrow. This one is still in use in the Danbury Railway Museum railyard. It has patent dates of 1927 and 1928 molded into its cast frame. And it was manufactured in Hilburn, NY.

Actually here in Aus we would call this type of derailer "Catch points" catchpoints are used exyensively on our system at junctions. with the catchpoint open (derail position) we can allow a train to approach a junction while movements are occuring past the catchpoint and signal. This allows closer train running, if no catchpoint is protecting a junction then a train would be required to stand 2 signals clear of a junction

My one picture link on this thread is fixed.

I am surprised this hasn't received more attention. How would we get trains to their proper destinations without these and their remotely controled and/or automated cousins?
