Flexibility

Because the engines are modular, flexibility is obtained:

  • If one engine fails, the others can continue at reduced power.
  • If a lower axle load is needed, one engine can be left off.
  • When reduced power is needed, one or more of the engines can be turned off, saving fuel and wear and tear.
  • The QSK19C engine is common to the four variants of the NRE 3GS21C engine.
  • The QSK19C engines from Cummins is widely used for non-railway applications, and spare parts are readily available.[12]
gollark: They don't need to be on the same frequency or anything, you could just have a device with multiple transceivers.
gollark: You also pay them for lots of abstract things you can't really see, such as "law enforcement".
gollark: You would still need an antenna which receive do the frequency you want well, though.
gollark: RTL-SDRs are cheap and do something like 20-1700MHz.
gollark: According to the interweb it can do a few tens of Mbps.
