UP 2-tone grey 4-6-6-4 challenger;  Tenshodo 1999 release final assembly and CNJ 4-6-4T assembly.

UP 2-tone grey challenger final assembly.

video: 'yard test'.  The engine sound 'cuts off' for a few seconds: must need to clean the wheels!

Wire routed for the head light with 2-pin connector.

Testing.

Another set of motor wires (orange/grey) from the back motor to the front motor.

2-pin connector for the front motor.

2-pin connector for the rear motor.

Heat shrink tubing to protect the wires.

Multiple pieces of 'heat shrink' tubing to the front motor for 'flexibility'.

4-pin connector from frame to boiler. The green pin not used as I didn't install LED's in the marker lights as I didn't want to drill holes into the front 'smoke box' cover.

Had to caulk one piece of lead weight that 'fell out' during disassembly.

Reinserted another piece of lead weight in front of the 'back head'.

Unusual place for lead from the 'builder'.

All wires taped to the top of the boiler.

I used multiple pieces of 'heat shrink' tubing to route the 'running board' lights to the top of the boiler.

While testing the decoder I noticed sparks and smoke coming from one of my 8 pin connectors.

I 'lucked out' as I thought, for sure, it would 'smoke' the decoder but nada.

I had just connected the front engine for testing when the 'smoke' occurred so I figured I hosed 'something up'!

After diagnostics, I found that the 8-pin connector was defective as 2 pins were touching each other.

I used my voltmeter to check all the wires and found that the grey and black wires (2 pins next to each other) had internal defects.

I was going to unsolder all the wires but the 'light bulb came on': hey stupid, just cut off the old pin connector and install a new one!

Retested on the programming track and all's 'good' 

Re-assemble, again!

8-pin connector from engine to tender.

2-pin connector between the 2 motors.  This allows 'ease of disassembly' for any future PM.

Program test, again, after attaching the rear engine to the boiler....

and, again, after attaching the front engine to the boiler.

Front smoke box cover is a 'friction' fit.

This plate that goes on the front smoke box fell off during disassembly.  Will use caulk to secure it.

All exposed wires taped.

There are 3 steam lines that are secured with screws for the front engine to 'articulate'.

BEFORE:

Pilot and boiler was damaged.

Front engine was 'binding'.

Cab roof badly damaged.

Dents on the tender.

AFTER:

This was my first 'job' trying to restore such a badly damaged engine.

Tenshodo imported a few of these as 2-tone grey so I painted this one a 2-tone grey.

I had one original 'elephant ear' from Tenshodo but had to make a duplicate for the other side.

Running board lights added.

Fire box glow.

Cab light added.  Nicely detailed interior.

2 head lights plus marker lights added.

Engineer's side.

Wore out my soldering iron tip!

CNJ 4-6-4T assembly.  Imported by PFM (United) in 1969.

Running gear assembled to the frame.

Caulked the new can motor.
