I am another of those that find it interesting and memorable to have names on whatever transportation conveyance I happen to be traveling on. It is much easier to recognize a name then some multi-digit number. Many times I have boarded a train, and seeing the car name, smile to myself, having recognizing it from a past trip.
I like when the names have particular significance. The Pullman Company would name a particular series of cars of the same configuration with the same prefix or suffix to readily identify their type...such as "Ashtabula Inn", or "Sunbury Inn", "Inn" identifying it as a 21 Roomette car. Or "Kankakee River", or some other "River", "River" identifying it as a 10 Roomette, 6 Double Bedroom. "Imperial" this or that was a luxury 4 Compartment, 4 Double Bedroom, 2 Drawing Room car.
The list goes on....
I especially liked the names of Burlington cars. They named virtually all their long distance equipment. In early years, they named their Zephyr motive power, as well.
The Burlington prefixed their cars with "Silver", and then individual cars were given similar series of names according to car type. For example, coaches could be "Silver Colt" or "Silver Mustang". Diners could be "Silver Restaurant" or "Silver Banquet". Dome-Lounge-Sleeper-Observation could be "Silver Lookout" or "Silver Horizon".
My personal favorite name of all named railroad cars is PRR California Zephyr Pool Service Car "Silver Rapids". It was the only CZ car not owned by the three operator's of that train (CB&Q, D&RGW, WP), but represented PRR's mileage contribution to the coast-to-coast thru sleeper. Its name was doubly significant, as many of PRR's 10-6 Pullman's were named in the "Rapids" suffix....
