76,000 Liters sounds like one tank car ruptured, and lost about 2/3 of its load.  When a pipeline ruptures, (pipeline leaks are a bit less than half as frequent as tank car derailments), the typical loss is about five times that.
.
While pipelines leak less often, each leak tends to be much bigger.  Overall, railroad tank cars and pipelines are about equally risky for the transportation of oil.  There isn't that much to choose between them.
.
But, to put it into perhaps more meaningful perspective, they are each more than a hundred times safer than shipping by tractor-trailer on the highway.
