SILIGURI, 24 AUG: The Darjeeling Himalayan Railway is observing its 128th anniversary in collaboration with the North Bengal Science Centre through a slew of programmes including a photo exhibition showcasing the spectacular history of the toy train, now included amongst the Unesco world heritage sites. The postmaster general, North Bengal and Sikkim region, Mr Lalhluna, inaugurated the week-long exhibition being held on the NBSC premises. The joint director, tourism, West Bengal government, Mr Gopal Lama, the principal, Siliguri Institute of Technology, Mr S Dasgupta, the project co- coordinator, NBSC, Mr Rajib Nath and the director, DHR, Mr Subrata Nath were present. According to the DHR director, this year's programmes were kept low key in view of the indefinite postponement of the heritage service between New Jalpaiguri and Kurseong due to lanslides along the tracks. “We would celebrate the anniversary in a befitting manner in future,” Mr Subrata Nath said. Referring the frequent landslides in the hills, an octogenarian ex- DHR employee, Mr D B Thapa, who was felicitated on the occasion, issued a note of caution. “The unimpeded traffic flow involving heavy vehicles along the fragile hills might bring about natural calamities of grimmer magnitude in future. Those who love the hills must come forward to checkmate the unhindered vehicular movement to avoid a catastrophe,” Mr Thapa commented.
