I posted this last night into the thread about Williams FA's and thought it might reach a wider audience here as a fresh topic. Many of you and especially newcomers will probably consider upgrading Williams engines at sometime or other. Williams engines are excellent values for the most part as a conventional running piece. They are virtually trouble-free and will run 'forever' pulling more cars than you might have room for. They are simple, utilitarian, and colorful in the many and varied road names/color schemes available over the years.
A cautionary note for those contemplating adding a command system and especially one with sound to a Williams engine thinking it is a 'cheap' proposition. Most seem to think that it is relatively inexpensive to do so but consider all the components to this proposition -
Assuming you probably already have the Williams in your roster is a given but consider the whole project as if starting from scratch-
*The Williams engine itself, which can be a single unit engine (Geep, FM, SD, or similar) and can be found on sale New for as little as $99. Previously owned for even less.
*Now add the cost of TMCC & ERR Cruise at about $119/$129 and you're in for $220 or so with no sound (assuming you did the installation yourself).
Add Sound for another $100 and you have a $330+ engine. If you are doing an AA or ABA set add another $75 - $150 to the basic engine. (That's $450+ for an ABA)
*Using MTH's PS2 may be a better alternative because the sounds are built into the kit available for $150 - $180. Some of you can do that installation but most will probably opt for a 'professional' job adding another $100 to the cost. Either way you now have $350 and up for a PS2 command single unit engine with sound.
And neither of these has smoke (add another $25-$50)
I would suggest looking into the 'used' market for good Lionel, MTH, Weaver, et.al. engines with command and sound that can easily be had for $150 - $200. I recently picked up on a NEW Legacy Southern U30C for just $325. Same $$$ as a Williams conversion...but no comparison to a Williams U-boat.
Williams has the advantage of simplicity and a rugged drive train that is attested to by all but generally lacks the finer detail of the competition. This may or may not be important to you. I'm considering adding command and sound to my 'newly purchased' Williams FA's in PRR livery because I obtained them at a very good price (used), they actually look quite good in the dark green color, and I have several command set-ups on hand available to install.
If I was starting from scratch I'd definitely buy 'used' Lionel or MTH however.
