Kato Test Track — Speed Matching Batch #1 Continued

Next I speed tested the two UP SW7 units #1800 & #1824. Although They were the same loco as CBQ #9255 by the same manufacturer their speed were not quite the same.

CBQ #9255 was set as:

  • CV5 set to 130 giving a Top Speed of 80mph at speed step 126
  • CV6 set to 60 giving a Speed of 41mph at speed step 63

However UP #1800 had  to be set as:

  • CV5 set to 140 giving a Top Speed of 81mph at speed step 126
  • CV6 set to 65 giving a Speed of 41mph at speed step 63

And UP #1824 was different again and was set as:

  • CV5 set to 141 giving a Top Speed of 81mph at speed step 126
  • CV6 set to 65 giving a Speed of 41mph at speed step 63

The two UP SW7 units #1800 & #1824 will become a consist and will be permanently joined together. However I will get into consisting at a later date.

Time to move onto Batch #2 – three Atlas EMD GP30s.
