No. They will be run by themselves.
There's four groups of LRVs, as far as technical specifications go:
- Original U2s (83 units, 3 of which have been retired). These run on DC power and generally run only with each other.
- AC demo U2s (2 units). These run on AC power and Calgary Transit mechanics rewrote the control system software so that they can be run either with each other or with SD160 units. You will sometimes see a 3 car train that is either these 2 plus an SD160 or two SD160s and one of these two units.
- SD160s (72 units). These run on AC power and run either with each other or sometimes with the 2 AC U2 units.
- SD160 series 8 (38 units on order). These are the brand new ones. Due to having a different coupling system, they will run with each other. However, it is thought that they might run with the older SD160s once in awhile, with the new SD160 being run as the middle car in the train. That probably won't happen for awhile though, if ever.
