RR station appurtenance question ...

[eja]

If i recall correctly, (doubtful at my age), someone used to sell an N scale product that replicated the yellow strip with raised bumps that one sees on railroad station platforms.

Can someone refresh my memory regard who made these and/or if they still do ?

Wheels of Time has decals to simulate the ADA platform warning bands (aka tactile paving or truncated domes): http://www.wheelsotime.com/details/
Walthers shows them as in stock, so they should be readily available.
