Several Retro-Futurism visions of the 1930s.
About these propereller driven monorail transports, they would use diesel or kerosene fuelled ⛽️ engines that would make them reach very high speeds, yet this vision/idea and as seen in the image, had no protection should something go wrong like derailing…so having "nerves of steel" would be necessary 😵💫🤢😱to say the least…😊
