Spotting markers for undertrack magnets in a yard

[rrebell]

Thought this thread was dead? But since I have not done this task yet, all info is appreciated! What era were the blue flags used?

One very realistic possiblity is a flip up blue flag. They are common on yard sidings both in engine service areas and car yards. They will be inclose proximity to the siding's switch and are often placed where a derail would be placed.

The only problem with using a blue flag is that, to remain prototypical, the blue flag must be removed to allow train movement past that point.  A yard with all of its tracks blue-flagged wouldn't be of much use in keeping the system fluid.

 I have just found this link in another forum showing an LED alongside the centre of the uncoupler

So as a further development. and using the "blue flag" idea, if you "nearly bury" a blue LED alongside the uncoupler and power it with a push button so you can see where it is but otherwise it should not show ...

Just an idea

for magnet location on my old layout [1960's], I used a bit of yellow paint on the raii side to mark .. on the new one [1890's] I use craft box  yellow glass tube beads with a pin in some areas, in other I use part of a small tree, cut at equivalent 6 to 8 foot height, a tree cut down because it's too close to the track ...if I look close I can see the supermagnets glued between the ties, they are not ballasted, just painted a close colour to the ballast..
