I have two batteries in my Battery Grip and so far I have not been let down. Even when cold, I have taken 300 or more pictures, and when I get home the batteries still have a half charge.
Thanks everyone for all the comments! As far as the train goes, I would have to wait days for "The Royal Canadian" to pass, as it is the only converted steam engine that travels that mainline. All the others are deisel locomotives loaded with freight cars.
I will keep trying though, and if I can catch the steam locomotive, I will retake the picture, especially for you!
Have a Happy New-Year!
