If you’re a fan of spotting Google Doodles, this is a great week for you. A day after Google honoured Swiss mathematician Leonhard Euler with a doodle, the search giant has come up with one more to commemorate the 160th anniversary of the first passenger train in India.

The doodle is a simple affair, with a steam locomotive pulling a train. The engine forms the first “O” in “Google”. The whole doodle wears a very old-worldly look and resembles a painting more than a drawing. The train is surrounded by open fields and palm trees, trying to bring back the charm of the 19th century.

The first passenger train in India ran between Bori Bunder in Bombay and Thane on April 16, 1853, signaling a new era in travel and communication in the country. The train was pulled by three locomotives – Sultan, Sindh and Sahib and had about 400 passengers on board its 14 carriages. The journey of the first passenger train in India lasted for a good 57 minutes between Bori Bunder and Thane and had just one halt.

Interestingly, this was only the first time a passenger train was run in India. The first rail line had come up near Chintadripet Bridge in the then Madras Presidency in 1836 as an experimental line.

After the first passenger train was run between Bombay and Thane, the first passenger railway line in north India was opened between Allahabad and Kanpur in 1859.

The train doodle is a slightly less interactive one this time round and slightly inaccurate too, given the fact that the train was actually pulled by three locomotives.

To celebrate Euler’s birthday yesterday, the doodle was a partly animated one. The doodle included geometrical figures and mathematical formulae, scribbled on a partially yellow piece of paper. Some of the mathematical elements on the doodle, included the mathematical constant, his polyhedral formula, now written as v-e+f=2.
An important name in the field of mathematics, Euler's genius can be affirmed from the fact that he is the only mathematician to have two numbers named after him – the Euler's number in calculus (e, i.e. approximately equal to 2.71828), and the Euler's Mascheroni Constant (gamma), also called as “Euler's constant” (approximately equal to 0.57721).

Earlier in December, Google had honoured another mathematician, Srinivasa Ramanujan on his 125th birthday. The doodle in the memory of this genius was endearing, to say the least and best described what Ramanujan lived for – his love for mathematics. The doodle showed a young lad, believed to be young Ramanujan, on his fours, writing the mathematical constant Pi, which is approximately equal to 3.14159. The word 'Google' was thoughtfully etched out of the different formulaes and other mathematical depictions.
