This engine is running smoothly and has operated in a consist with a SD70. I received engine #6043 last week, but have not received engine#6049. I Also have two of your 4-8-4 engines, American Freedom and Independence. I tried sending a picture of them , but I had trouble with your email address. I have a suggestion, if you can create a 4-8-4 based on your T1, but labeled Confederation for Canada, possible engine #0701, to commemorate Canada Day.
