This is from my post from another section here in this Topic: As Follows:
I ordered two Lionel Legacy ES44AC Engines in Santa Fe Livery. After waiting for them to be delivered to me, I finally was able to run these engines on the club layout that I belong to.
First problem was that the thirteen K-Line Hi-Level Passenger Cars and these two engines used 19 volts and 9.8 amps as displayed on the display panel of a MTH Z-4000 transformer.
So, I purchased LED Light Strips to retrofit the K-Line Stream Lighting that was installed.
The cars, using the K-Line numbering for the cars, are as follows:
Transition Car #3482, Hi-Level Step Down Car # 535, Two Bi-Level Cars # 526, Bi-Level Car # 529, Two Diner Cars # 651, Two Bi-Level Cars # 536, Bi-Level Chair Car # 529, Hi-Level Step Down Car # 535, Transition Car # 3482, and the Mountaineer Business Car.
After the conversions, the engines and the modified passenger cars displayed 18 volts and 3.8 amps on the Z-4000 transformer.
Now, the club layout has two different lines. The Red Line is the one that is built as a line with passing sidings. The Blue Line is one built where one train will follow the other several blocks apart.
On the Red Line when the engines are turned into the sidings, the front truck of the lead engine jumps the switch and, of course, displays the red light for a short. We removed the following cars to lighten the weight the Legacy Engines were pulling. The are as follows: Two Bi-Level Cars # 536, Diner Car # 651, and one Bi-Level Car # 526. With the less amount of weight on the engines, it still caused the lead engine truck to jump any switch it was set from through to turning in.
After several attempts, we switched to the Blue Line. This line is setup as a train following another with several blocks separating each one with less switches. Using the same consist with the four cars removed, the two engines were able to pull the passenger car load.
Now, the following questions.
Question One - With Two Engines - I should have been able to pull all the cars. I am very upset that two engines could not pull this load. You would think that two engines should have easily pulled this load.
Question Two - I will try the full consist with two MTH Dash 9 engines. If this consist works, I would be surprised if a different manufacturers engines can pull more load.
I will post another reply when I try out the new consist as stated in question two. If two MTH engines can pull the full consist and Lionel's cannot, I would not be inclined to purchase Lionel products in the future.
