2018—Mursina, Kate (8 February 2018): "Teasing Out Circulating Tumor DNA". ClinicalOMICs.

Considerable activity on CTC projects will occur during the year. Several roads are well along on programs of CTCing their mainlines: AT&SF, C&O, CNR, NYC, NP, SP and UP. 1960, Railway Signaling and Communications - Volume 53, page 16:
Back in the early 80's when Amtrak was CTCing the Northeast corridor the operators union (BRAC) notified Amtrak that only they could operate CTC on ex PRR lines. 1999 July 3, Erich Houchens, “NYC, PRR and CTC”, in misc.transport.rail.americas (Usenet):
The control of NS yards in Lousiville is a first step of CTCing the entire line from Danville to Prinston. 1995 February 12, krjo...@ulkyvx.louisville.edu, “Monitoring CSX and NS in Louisville, KY”, in rec.railroad (Usenet):
That installation will deplete telegraphers jobs considerably. Santa Fe already CTCing Mojave to Barstow. 1959, Trans-communicator - Volume 76, page 39:
This is something of a stretch. Yes, CalTrain is already safe, but, like I said, it is behind the times compared to other railroads. Part of improving service will involve CTCing the whole 47 miles of line. 1997 May 10, Kevin013, “Should CalTrain Drop "Push-Pull" Operating?”, in ba.transportation (Usenet):
