The screeching hooves on a black-board sound penetrated Ksirafai as his mind was busy thinking...It was a distracting sound to say the least, and the horde of ponies who rushed to check it out...He was smarter however and stayed put, making himself as small as possible to let as many ponies come in front of him as possible. He saw them rush past him, big, small, bulky, tiny. They all seemed to blend together in front of him, a maelstrom of shapes and colours. But where did Marionette go? Perhaps she was in trouble? 

The Train to canterlot was old, and as an old train it had several poles witch ponies could hold on too. These sat a convenient places and above the seats. So, it was quite easy for a nimble horse like Ksirafai to grab hold of one of these and climb above the rush of ponies looking for Marionette among the shapes.
