I am a little confused. So, the Glacier Express runs in Switzerland, the Darjeeling Himalayan Railway express runs in East India, and the Trans Siberian runs in Russia and the far east. None of these have much to do with Delhi to Goa though. However, if you meant that just like these 3 fun train journeys, you would like to experience something similar while going from Delhi to Goa, I am sure we can find something amazing for you. Numerous trains run on that route, however, I am not sure which one would suit your taste the best. Also, if you do want to add an amazing journey, you can take the Palace on Wheels which runs along western India. OR you could wait a while for the Delhi to Leh railway line - believe me, this will be the best train journey to go on.
