Purvanchal Express - Poorvottar ka Sikandar

Hello all, i have to book sleeper class ticket from Warangal to Villupuram for 4-5 passengers. Even for the farthest bookable date the number of tickets available in all the trains are very very few like only around 10 - 12 tickets are available, even in 3rd and 2nd ac its the same case. Why is the quota so less ? I tried checking from Nagpur still its same, from Vijayawada almost same scenario, my concern is if i book the ticket as the availability is so less i might get berths at different places. Any suggestions, among the 4 people i am the only guy other 3 are my mom and her sisters around 50-55 years of age, it would be best if all 4 of us can get near by berths or next to next. Train fans and experts help me out 🙏😊
