hello again, and yes in fact i am using A & U terminals. i have thought about raising wire size to 14 gauge wire...in hopes this will increase current to track. as for the loco...(681 not 671) typo,,, i installed new brushes and cleaned commutator about 2 years ago. the tender i have cleaned relay contacts and lubed motor with lionel brg lube...other than that, not much i can find wrong. i do have a newer MRC powerpak...not sure of watts output,but they seem to run the same.  going to try larger wires to lockon and add a second lockon on opposite side of track...thanks for the help Smile

Survivor, are you sure you have the power lines to the track hooked up correctly, that is the "A" and "U" terminals on the transformer?  You may want to meter the track to be sure you're getting up to 18 volts AC.  If the power's OK then the locomotives may need a complete teardown and cleaning, best to let a Lionel service center handle that one if  you're not sure how to do it.  Back to power, I hooked up a Lionel KW transformer to the Christmas tree loops and it took me a while to figure out just what went where, I hadn't used it in almost 30 years!

Welcome to the Forums!!Welcome

For an answer to your question, you would do much better on the Classic Toy Trains forum, they deal with Lionel,etc over there...this is mainly for 1 to 1 scale trains.

lionel TW transformer
Posted by survivor on Friday, January 13, 2012 4:51 AM

hello all, this is my first post in this discussion group,i hope someone has some insight. i have an old lionel TW transformer...and a 671 S2 loco with prr whistling tender. this set has been around since the mid 50s when i was a kid, i remember the whistle blowing sharply,and the engine running so fast on a 4x8 layout, that sometimes it would derail on turns. recently,i drug the set out of storage,disassembled engine and tender,lubricated all moving parts...(with lionel lubricating oil and gear grease) .now,my question is this...i am familiar with the mixed AC/DC voltages this TW produces, to run train and blow whistle...now,when the whistle blows...the train slows down considerably...and,in all...the loco doesnt seem to have the umph it used to have pulling a light 5 car freight.now i would think looking at todays transformers...175watts  should be plenty of power for a small layout and mall train /car combo. i also have a few postwar NW2's.....they seem sluggish as well. i am running new tubular track, and i have checked and tightened all track/pin connections with track pliers. also have tried doubling up with lockons to even out power  to track. now this is small...a 4x5 layout...so i wouldnt think power should be a problem. is this old TW just 'givin up the ghost'??? is it possible its ac output is failing.....or maybe bleeding dc current in while train is running?...(note,sometimes whistle seems to intermittently tweak while train is running at full power)   any help would be greatly appreciated. thanksSmile
