PC board & suspension springs

[steambuff]

I removed the pc board in the tender and loco  (K27) i needed more room in both in order to install batteries in the tender and a pulsed smoke unit in the loco,a few years back i installed a super smoker actually designed for ships,it has quite some puff to it,
while working on the K 27 i noticed that all of the suspension springs have collapsed ,does any one know which size they are,or better where to get replacement with some stronger springs?

Contact the service department to see if they have any replacement parts
