I go for Lionel LW 125 watt transformers. Up to 20 volts output I believe.  I have three on my layout, two of the LWs often run two trains per blocked, relayed loop.

 

Lighted dial indicates track voltage and brightens as voltage is increased.  LWs  can be had for $35 or so.  I believe LWs are the best watts per buck transformer out there.

 

Enough transformer for most any train if used for trains only.  I use other transformers for accessories and lights, etc. 

 

Note:  The LW lever increases voltage counter clockwise which is opposite of many other Lionel transformers.  Mixing LW and others can lead to confusion.

I have two postwar ZW's on the current basement layout and a KW on my son's layout (which is underneath mine in the basement).  I used to use three Z's for previous layouts and I plan on using those again for a 24X9 attic layout over the garage that I have been slowly building.

 

I use AF 8B's (5) and a 12B for AF stuff and have a couple of 150 watt Marx transformers as well.  Even had to get a Marklin ho type for some 3 rail ho fun....  I have TMCC and about 5-6 TMCC engines and one Legacy diesel.  Might get legacy one day if I ever land either the K4s or E6 with whistle smoke

I run my Standard Gauge loop on a postwar TW. A TW puts out a bit more voltage than some other postwar transformers, so it is handy for the occasional prewar locomotive that likes a few more volts. The Standard Gauge is equipped with TMCC to run the Lionel Hiawatha, but I did not bother to connect it to the DCS unit because I don't own any Standard Gauge locomotives with DCS.

 

My Standard Gauge is an outer loop running around an 0 gauge layout with three main lines. Two of those are powered with a Z-4000 and one with a K-Line Power Chief (yes, there actually is one of those that works, and yes, I did have to take it apart and fix it).  

The 0 gauge is equipped with both TMCC and DCS.

 

The Standard Gauge layout in our toy train museum is powered by two original 250 watt Z transformers. 

Either a Z, V, or LW. The Z and V are very robust, and put out over 20V, and are great for heavy, standard gauge trains.They can handle a great deal of load. You'd need a whistle/reverse controller with these if your stuff has whistles.

 

In my opinion, ZW's lack a little, and KW's are not a good choice for running standard gauge tinplate.

Ready for more power.

I use 2 Z-4000s and 1 Lionel 180w brick. Everything is pretty much at there limits on my STG layout. 1 throttle on the outer loop can run 8 car Brown State set with 408E plus Super 381E with 5 green State cars about 8 or 9 amps at 18v. 2 more big sets on the middle loop pull a little less power depending if I run Passenger or Freight. The inner loop is a figure 8 so it only runs 1 train and uses less than 5 amps. The 4th Z-4000 throttle is pulling 9 amps at 18v for lights. The Lionel brick pulls 9 amps at 18v for more lights. The Z-4000 pins power the TIU,switches and signals.

 

I have 2 KWs on my O-gauge layout and can not imagine why a 175 watt transformer with full power at 20v is not good for STG.

V's and Z's have a voltage range of 6-24 volts compared to the 6-20 volts for the ZW.  While they technically have the same rating, 250W, the Z does it at a higher voltage and that probably helps with the natural voltage drop around the old tubular track.  All I know is when I used to run the Z's, I could really highball multiple twin motor loco's with a long string of cars....  Those babies can make a train really motor.... I do like the Prewar Z the best.

I use Z's, ZW's, Z-1000's, Z-4000's for track power and rewired, reinsulated and fused T's and K's for lights. I also use Variable voltage 5Qty 30amp DC industrial power supplies for lighting and accessories. I separated steady on lights and accessories from blinking lights and accessories because I hate to see a streetlight or house with a slight blinking to it.

Every KW that I have come across has had less than 20V output, normally at or a little above 18V.
 
The original standard gauge trains are big, heavy, and really can easily use 20V no problem, which is the limit of a ZW. The added voltage capacity of the V's and Z's provide more operating range for the trains. They like more power, and these early transformers can provide it. They're pretty cheap, too.

Why not the KW? I don't use one for Standard Gauge, but I have a couple of them and I'm curious why you think they are not a good choice. 

I'm with WindupGuy - the CWWK's are simply the best - rugged, foolproof,and you never have to worry about a power outage.  They come in a variety of finishes - the Marx as illustrated - are plain and functional, Flyer and Ives, while utilitarian do have a little more in the way of visual appeal. The foreign stuff - Bing, KBN, etc. while just a rugged really does tend to go overboard when it comes to the visual impression.

I have 3 loops of Standard gauge currently.  I use 2 Lionel Type Z transformers, one for each loop on the lower level and an original Lionel K transformer for my upper loop.  I also have DCS and TMCC wired through the whole system.  I protect my modern electronics with in line fuses prior to the TIU.  Most of my trains are original prewar, but the DCS works perfect on the two circuits that lets you change voltage conventionally.  I use the TMCC for the Commadore Vanderbilt and the Hiawatha.
