Study each of the following case carefully. Briefly state the principle of law and your decision.

Crowley, a building contractor, ordered 500 bags of cement from Litvak Building Supply. It was agreed that Litvak would deliver to a building site, and title would pass when delivery was made. Before the bags of cement could be loaded on a delivery truck, a train derailment destroyed much of the supply company’s inventory.
a. Must Crowley bear the loss and recover damages from the railroad?
b. Is the requirement of delivery to a building site a condition precedent?
c. Did title to the bags of cement pass at the time the order was placed?
