Got her down to a 1.62 few weeks back
before putting caltracs on and still trying to catch back up on the 60' ever since.
however,
last Thur night coming off the line..... well about 20 ft down the track
broke the axle.
Already fixed it... long day yesterday, hopefully it will hold together, if you look at the close up you can see what looks like manufacturing defects in the axle.
The 390's certainly have the potential to be sticky.
Now the caltracs.. they are still eating my lunch on how to get back right.
