Title: Lionel HO Burlington Northern 181 Diesel
Post by: hap on June 26, 2008, 01:04:07 PM
In trying to revive my old train set for my 5-year-old, I'm looking for replacement parts for the above engine.  A local model RR shop suggested that it might have been manufactured by Bachmann for Lionel, which led me to this site.

The markings on the bottom are "c1976 Fundimensions".  The problem is a dead motor, which sits upon and rotates with the front truck and does not apprear to be separable from the truck.

Any information regarding who made this engine or where I can find parts would be appreciated.

The type of motor in your Lionel is a "pancake motor", a notoriously unreliable piece of equipment. It would  probably be better to simply buy a newer locomotive with a better motor. If you do really want to run the locomotive, try looking on ebay for a similar locomotive you can cannibalize parts from. Bachmann has updated all their pancake-driven locomotives, and thus, is highly unlikely to still have any parts.

 Lionel HO was manufactured by different companies.  The sp 4-8-4 was made by Bachmann.  However the diesels I have were not made by Bachmann.  They do not have the pancake motor.  They also have 8 wheel drive.

Thanks to both of you for your replies.  I actually found another copy of this engine "new in box" on Ebay - we'll see what happens.  Even if it's unreliable, it's important to me to have "my" engine.  If my boys really get into the model train thing, I'll buy them a new, better-quality engine and put mine up on a shelf before they wear it out.

Curious - what does the 4-8-4 nomenclature mean?  In case it's not obvious by now, I haven't played with model trains since I was ~10.

In steam locomotives, the first number is the number of unpowered leading wheels, the second number is the number of drive wheels, and the last number is the number of unpowered wheels. Thus, a 4-8-4 has 4 unpowered wheels, 8 powered wheels, then 4 more unpowered wheels. Some locomotives, like a 4-6-6-4, may have four numbers. In that case, both of the middle numbers of wheels are powered. thus, the 4-6-6-4 has four unpowered wheels, 6 powered wheels, 6 more powered wheels, then four more unpowered wheels. Most wheel arraignments also have a nickname as well ( a 2-8-0 is a consolidation, a 4-6-2 is a pacific, etc.).

Diesel and electric locomotives use a different method. Powered axles (not wheels) are represented by a number, while numbers represent unpowered axles. A 2-C-2 locomotive, then, would have two unpowered axles, three powered axles, and two more unpowered axles (if this locomotive were a steam locomotive, it would be 4-6-4). Nearly all diesel and electric locomotives nowadays are B-B(4-axle) or C-C(6-axle).

It's a somewhat confusing system, but it is logical.
