Sow's Ear part Five: Mantua (Tyco) Pacific 4-6-2

This is Where It All Began, Patient Zero, the Adam of my railroad population. The head engine of the original train set bought in Christmas 1972. 
Still runs, but like other things its age, has problems getting up to speed and going up hill. While this old model resembles many prototypes, it hasn't the level or selection of details to replicate any one. It does appear that it could be brought within shouting distance of an ATSF 3400 series locomotive primarily through addition of details, and made both reliable and dcc ready by an off the shelf repowering kit.
1. Repowering.
I bought a repower kit from cv-backshop on eBay, who produces can motor and flywheel upgrades for a wide range of older ho locos. The product, service, and communication were excellent, the installation was simple and straightforward. 
The old open frame motor is removed, the worm gear pulled and reused on the new assembly which is glued in place. Fits like a glove. Just be careful with gear alignment before the adhesive sets up. And since the motor leads are isolated from the case, dcc conversion will be straightforward. 


2. Prototyping.
First on the list is the pilot. The Mantua pilot is not Santa Fe style, but one can be obtained in cast brass from Precision Scale (sourced on eBay). The "shield" on the pilot will have to go.
Original on left, replacement on right. The shrouding between the ladders must go...
Razor-saw that shroud away

Remove, the pilot beam, Replace missing platform

ACC the replacement in place

Fit up on the engine.
Of course, it now needs the air tank and piping hidden by the previous shroud, and an appropriate coupler added.
