Those 6 are all that they had produced.
The trains seem to be clustered in the mornings now. It is a chilly winter. I am not going to wait for an approaching CN train to see if the GTW unit is approaching until the spring.
For HO scale ATHEARN plans to make the CN and GTW SD70M-2 units first.
It is good that Lionel team is not able to get them in production immediately. I a few older locomotives that I have to get first in O scale.
