The mighty veteran Purulia Express serving for decades, daily commuters' lifeline and witness to a Rising Bengal! - Soumyadip Mahato

Thankyou very much sir for very nice explanation. Thus, from such a lengthy debate/discussion from this blog......it is now very clear that
1) Regional train name can be written on IRI in regional (or local) language...
2) Regional name can be written in Devnagari script though it similar to hindi.....bcoz
i. It is not fare to club all languages as hindi that uses devnagari...
more...

script.
ii. Regional name in Devnagari script will make people know that regional language uses devnagari script, whereas,
iii. If we keep it simply blank the people will not understand that regional language uses devnagrai script.....rather this may feel the people that 'regional name is not updated on IRI'.
3) Regional train name can be written in regional language of source station followed by regional language of destination station.
....
If any #Monitor / #Admin has any objection on this....PLZ comment.......otherwise here onwards PLZ consider these before updating the train name TLs.
