I just finished a shift charging the dock job. Freezing rain the whole night. We had the 3000-3009 U30s and had some trouble with them starting out. The 3009 kept shutting down. They are so old a leaky that I think something was shorting. They were also having trouble spotting on the dock due to wet rail and flaky air gages. Anyway if you want to see the U30s they are being used on the dock for the time being at Marquette.
