LUCKNOW: Senior citizens women passengers above the age of 45 years and pregnant women travelling alone in trains will be able to book four lower berths in a sleeper coach instead of two lower berths. The reservation quota so far allowed passengers in the above mentioned categories to book two lower berths per coach in Sleeper, 3AC and 2AC classes. But now the quota has been enhanced for sleeper class coaches. There is, however, no change in the number of lower berths earmarked in 3AC and 2AC classes.Passengers complained that in case of two senior citizens (husband and wife) wanting to book lower berths under this quota, they were denied the facility since they were travelling "together and not alone". Passengers demanded that the facility be given even when they are travelling together.The facility will be available to passengers who are both senior citizens, women above 45 years of age or pregnant women travelling together. Also, passengers travelling in combination like senior citizen travelling with a woman above 45 years of age or with one who is pregnant will be able to use the facility.
