What is the case for location custodiae?

Chapman v GWR - goods were sent to a railway station warehouse to be kept until called for by the plaintiff, who was a travelling salesman. When he called for them three days after they had been delivered, he found there had been a fire and the goods were destroyed. The railway company when transporting the goods were what is known as ‘common carriers’ with specific liabilities. Chapman sued them as common carriers but failed on that point because the court held he had left it too long to collect the goods
