The Ambala Division of the Northern Railway has resorted to the "wanton destruction of green cover at some of its railway stations, yards and even Divisonal Office in Ambala" on the pretext of "mobilising financial resources".Hundreds of full-grown trees, incliding an entire avenue of mango trees on Railway Road here, have been axed while hundreds of more green trees, including mango, silver oak, shisham and eucalyptus, will be felled in the coming few weeks in what is being described as "one of the major de-greening exercises undertaken anywhere by the Northern Railway since Independence".
