New York's bridges
Hi! I have contacted you folks before. I am working on a book on New York's Bridges. I have helped Wikipedia in the Past as I have made some important corrections on some of your sites and I have allowed Wikipedia to use some of my photographs on their sites. What I need to know in detail is How can I have my Attorney write up a small paragraph stating that some of my historical information was supplied by Wikipedia. I DO want to make sure Wikipedia DOES get the proper credit. Do you have any example's that you could show me and I can present that to my Attorney? Thank you!!

Myanmar Dual-gauge rail-tracks
What is the function (history) of this Dual-gauge rail-tracks? (19° 51′ 3.14″ N, 97° 1′ 32.64″ E, near Pekon)? Etan J. Tal(talk) 10:36, 2 March 2019 (UTC)


 * It's not dual gauge. The inner rail is a guard rail. These are often used along the inner rail in a sharp curve. If the outside wheel climbs over the outside track, which may happen if the track is of very poor quality, the train is travelling too fast or there is some mechanical failure, the back of the inside wheel will hit the guard rail, which keeps the train more or less on the track. This is safer and makes recovery easier.
 * Guard rails on bridges, where they are usually provided on both sides, help keep the train on the track if it derails. Check or guard rails on curves are primarily to help prevent derailments by pressing on the inside wheel so the outside wheel doesn't need to transmit the entire turning force. --76.69.46.228 (talk) 01:41, 3 March 2019 (UTC)
 * We have an article on rail transport in Myanmar, but it doesn't give many details. It does tell us this line is metre gauge and it indeed looks like that. Apparently there is a dual gauge tramway in Yangon and there are plans to build more dual gauge (standard/metre) railways for eventual conversion of the entire network to standard gauge.

 * How does one rename a file (picture)? Peter Horn User talk 02:40, 13 March 2019 (UTC)
 * The descriptions of the file also needs to be updated, including on Wikimedia as well. All references to dual gauge need to be eliminated. Peter Horn User talk 17:49, 13 March 2019 (UTC)
