I have seen the following trains having big typos either in English or Hindi. Most of them are not run by SR. I am sure even SR also makes mistakes as can be seen in the spelling of Nizamudeen !!
• Dhanbad- Alapuzha. The hindi version of Alapuzha is written incorrectly and also
• Guwahati Trivandrum is written as Trivendrum' !
• In case of Marusagar...
more... express previously Ernakulam was written as Arnakulam !!! This i think has now been corrected
