4-6-6-4 challenger and 4-8-8-4 big boy

[Anonymous]

Hi to all.

I preordered the n scale Big Boy last august at a friend's hobby store and have been waiting for a long time for it. My friends undecorated Big Boy came in two weeks ago and I got the chance to run it on the shops oval test track. It runs like a champ and the sounds it will make really add to the experience. You will not be disappointed with this engine.

 

I also have to agree with the others, why choose. Get them both.

[4-6-6-4 Challenger]

Hi everyone who has seen me around this forum I spelled my last accound wrong. It used to be 4-6-6-4 challanger but I made a new account 4-6-6-4 Challenger.  So you wont see 4-6-6-4 challanger anymore.  Just so you guys know.

I want to know about the real thing not a model.

I think he wants to know about models but I could be wrong.  If so you need to post it on the model forum.

Grade isn't the issue, they could climb any grade that any other locomotive could. They were designed to make better speed across the UP's Overland Route where ascending grades are about 1.5%. In addition the Challengers (4-6-6-4s) were used on passenger trains on the heavier grades, like in the Blue Mountains of Oregon (2.2%). The UP had a batch of 2-8-8-0 locomotives for slogging it out on regular freights over the heavy grades on the LA&SL AND the OSL.

Does anyone know what the max grade these locomotives can do?
