This is not an unusual train, but since Fr. Fred noted the dearth of more complex passenger operations, I thought it might be appropriate to mention the chapel cars. One of my daughters gifted me with the book, This Train is Bound for Glory, The Story of America’s Chapel Cars by Wilma Rugh Taylor and Norman Thomas Taylor. The idea of chapel cars to deliver church services to remote communities along the railroad actually originated in Czarist Russia on the Trans-Caspian and the Trans-Siberian railroads in the 1880s. The cars brought the Russian Orthodox mass to remote communities along those rail lines.
The first North American chapel car was built in 1890, but the final car was decommissioned as late as 1962. Denominations staffing chapel cars included Baptist, American Baptist (originally called Welsh Baptist), Episcopal, and Roman Catholic. The cars were considered part of the outreach and mission service by each denomination. The cars resembled a coach or Pullman, but carried names like Evangel, Emmanuel, Glad Tidings, Good Will, St. Anthony, Herald of Hope, and Grace.
About 1/4 to 1/3 of the car was set up as living quarters, and the remainder of the car was similar to a church sanctuary, with the alter/pulpit on the end nearest the living quarters and the seats resembling pews. No doubt the cars with smaller living quarters were used by one or two priests, and the cars with larger accommodations were used by a missionary/pastor and family. Most likely an upright piano or foot treadle type pump organ provided musical accompaniment for singing the hymns. The book notes that folks in remote communities along the line were glad to be able to attend church services, and the presence of the cars sometimes led to small community churches being started.
A chapel car would be a worthy project to model, and the book does provide scale floor plans in an appendix. Some furniture items for the car could be made using half inch scale dollhouse furniture. I have used it to make a business car from a Delton shorty coach. Folks adept with 3D printers could probably make some nice alter pieces, pulpits, and pews. A fun project would be to use a sound recording chip to record a hymn being sung.
Just thought I would add this idea to the “pot.”
Have fun, David Meashey
