 == CBTC projects update == 

 Hello, 

 I have noticed that some of our CBTC projects – radio based / moving block principle - were missing in the article.  
 Here are some example  Shangaï, Milan, Beijing, Mexico, Toronto, Dubaï, Panama, Hong Kong, etc. 

 As you are one of the most active editor of this article and already did an impressive work, I didn't want to be rude by editing these data by myself. 
 Then I have decided to forward you our data for your reference. 

 Should you need any additional information, I would be glad to help. 

 Kind regards, 
 S.Shirlaw
