Actual torn tape relays used two TDs per outgoing line. They ran in ping-pong fashion so you could load one while the other was transmitting.
Here’s mine in operation.
The sequentially numbered message header is inserted via stepper relay in this model. Earlier versions used an additional TD with a sequential header tape.
At the receiving end, a reperf/TD tape FIFO set could be used.

I love torn tape relay!!
…,,,,,,,Instead,
the line could continuously handle "tape speed." And, to me, torn tape
relay is an early form of packet switching.
A question on torn tape relay, when a new tape segment was passed to be
transmitted, was it spliced to the tape currently being transmitted so the
line would never sit idle, and no operator needed to load the next tape?
This, of course, is a FIFO buffer that handles bursty traffic input and
provides continous output.
