Bachmann Spectrum Mountain 4-8-2

The detail and the running gear are comparable to their first release, the acclaimed, Consolidation 2-8-0. Generally the 4-8-2 has been cast in the "same mold". Because it is larger than the 2-8-0, the 4-8-2 has good hauling power (10 Spectrum Heavy Passenger units over a 4% grade).

However, some of these early production units have been released that exhibit the following problems:

(A) Bent or distorted electrical pickup wipers on the loco's main drivers. There are eight of these phosphor-bronze wipers, one on each of the loco's main drivers that have been designed to wipe the inside rims. We found some of these wipers distorted and wiping on the spoke area. These can be repositioned by using a suitable tweezers.

(B) A chattering noise or sound related to the operation of the motor and drive linkages. Chatter increases with RPM and was more prevalent in reverse.

(C) Waddling or yawing of the loco side to side,probably as a result of a slight quartering intolerance. In most cases this waddling was barely noticeable and acceptable.

We are in the process of evaluating our stock and have been working directly with the folks at Bachmann to resolve the issues. They have advised us that the loco side rods and mechanisms are delicate and should be carefully handled. They also suggest the user to lubricate the side rods before steady running. I am confident that the 4-8-2 issues will soon be resolved to the benefit of all.

Note: The 4-8-2 uses the standard 2X4 NMRA plug assy. Any decoder with this plug will work for DCC operation. Soundtraxx will soon be releasing a special Plug n Play decoder for both Spectrums.

"HO" Spectrum 2-8-0 Steam: About 5% of locos released run rough. Return to dealer or Bachmann. Plug assembly between loco and tender are very delicate and wires can pull out easily. Because of circuit board in tender loco does not run well on ""DC" with decoder installed.

"HO" Most Spectrum Diesels: Split frame designs do not allow much extra space so "N" scale decoders are needed. Thin decoders like Lenz 103XF and NCE D102 will also work on several units.
