The Laboratory generates and stores research points. These can be used to research new trains or train upgrades for your current Era.

When you join a server in a later Era, the laboratory will start at the following level:

Era 1 Era 2 Era 3 Era 4 Era 5 Era 6
1 5 9 13 16 18


The table shows:

  • The cost of upgrading
  • The prestige points you get from upgrading to this level
  • The base time for upgrading (i.e. without the reduction you get from your Construction Yard or speed increasement of fast servers)
  • The time (in minutes) it takes to generate one research point (RP), without and with Researcher bonus (gold colored) and a percentage increase compared to previous level
  • The maximum number of research points you can store and a percentage increase compared to previous level
  • The average percentage of RP production and max RP storage combined
  • The time it takes before you reach the limit for stored research points, without and with Researcher bonus (gold colored)
