CTT Magazine had an article about this subject over a year ago. I don’t remember the date, but isn’t there an index to CTT articles somewhere on this site?
If you add a tire to an ungrooved wheel you will raise the hight slightly creating a wobble.
Replacing the whole wheel with a grooved one might be an option.
If you add tires to Two or more wheels you run the risk of loosing you ground.
i installed traction tires on my 736 bershire-it ran for about 5 loops before the tires started to come off- the engine ran and pulled better but without the grove on the wheel, you will have problems keeping the tires on-best way is to remove the wheels and machine the grove into the wheel.
The wheels are sintered iron. Be sure that you can machine that. You might want to experiment on a scrap wheel first.
I believe that the splines were first cut into the axles, then the axles pressed into the wheels, cutting splines into the wheels in the process. Although the wheels are not precisely quartered, the same wheels must go back onto the same axle, since the rotation angle between the axle and the wheels was not controlled. So keep track of your wheels after you pull them. (This is the voice of experience.)
The 2-6-4 version of the 2026 had wheels of different diameter. The middle, blind drivers were bigger. You could put traction tires on the rear drivers of that locomotive without any machining and still get all the wheels on the rails at the same time. Even if the locomotive you’re dealing with isn’t a 2026, its wheels or entire motor may be interchangeable with the 2026’s.
The CTT article recommended glueing the tires on with super glue after cleaning the wheel with alcohol. On steamers you would do the 2 rear wheels. I haven’t tried it though.
I believe our own Ben10ben once offered the idea of adding masking tape on the wheels to impove the traction. The tape is thin enough not to raise the engine too much and addeds the need traction.
Just trim the tape to the width of the wheel. let us know how it works.[;)]
Since real trains use sand to increase traction and decrease breaking, I wonder if we could do the same. If you attached a fine grit sandpaper to two wheels wouldn’t it both add traction and clean the track?
I probably won’t try, but it’s something to ponder.
Well gang, I have mentioned the idea several times in the past of using either 3M Traction Tape or a good quality electrical tape for traction tires on locomotive wheels that are not grooved. You will still have some slippage (on a steam engine this is nice) but it does improve traction. I know, I’ve done it for years now, but I do this with locos with AC open frame motors.
I’ve done some extensive experimenting with traction tires on locos with truck mounted Mabuchi DC can motors. For starters, these motors can be very inconsistant in operating speed even at the exact same voltage. I removed the trucks with motors, wired them to themselves, and put a bunch on the track with straight DC current and watched what happed. Speed can vary greatly.
I have removed traction tired on some locos entirely, like with my Lionel Industrial Switchers. Since the circuit boards have been pulled from them, I had room to add a great deal more weight. I called Lionel and spoke to a tech no longer there and he told me the can motor in the Industrial Switcher is the same identical model used in many steam engines with die-cast shells, so I figured the Ind. Switcher could handle the extra weight. And they pull like champs now… they will now pull 15 cars with die cast trucks, though that’s pushing the motor and I don’t normally operate like that.
On the other hand, I have pulled traction tires off K-Line S-2’s to find they needed them back on. Although some run better with a traction tire on each motorized truck and some don’t. K-Line has made their locos with the grooved wheels in every possible combination. I have found (as Lionel MPC figured out) that the traction tires seem to work best (esp. on dual motored locos) if they are on the same side of the locomotive, regardless of whether they are on both trucks or not.
I’ve also experiemented with altering dual motored locos into single motored ones. Again, some very inconsistant results. It certain does reduce pulling power, though
Back in 1948 I received my first Lionel, a single motored non-Magnetraction 2332 GG1. Needless to say I was not very satisfied with its pulling power, especially with the 30%+ grades I used.
I somehow got the idea to put standard masking tape on all the wheels of the power truck, since I still had 14 wheels for ground pickup.
The tape would last about a month with a lot of running taking place. It would get very gummy and black in color from all the oil on the rails.
That engine would climb a 45 degree grade easily and would snap the cars apart with its instant acceleration!
I’ve used tape on a 2056 steamer for years. (This is the 1952 non-magnetraction version of the 2046/646). The engine struggles somewhat to handle four postwar aluminum coaches; with tape on one wheel, it’s not a problem.
I’ve got masking tape on it now, but plastic tape (3M or whatever) works a little better. I have not had good luck with electrical tape – it seems to stretch, and something about the adhesive allows the tape to shift more than the other kinds. I’d avoid it.
First, clean the wheel tread with mineral spirits or rubbing alcohol (not as good, but OK). Cut the tape to about the width of the tread and long enough to overlap a little (maybe 1/4 inch?) when it goes around the wheel. The tape seems to stick better to itself, and thus lasts longer. Possibly other people might be more sensitive, but I’ve never noticed bumping or roughness from the overlapped tape.
Put the tape on one or both back wheels. One wheel gives me enough traction; I’d guesstimate something like a 40-50 percent increase with tape on one wheel. Two wheels gives a little more.
In my experience the tape lasts quite a while. Hard to even guess number of hours. I have a number of engines, so I don’t run the 2056 all the time, and I have temporary layouts (extended holiday set-ups lasting several months, plus sometimes an interim layout for several months between holiday layouts), but I don’t have to replace the tape every year, so I don’t consider lifespan to be much of an issue.
In general, it seems to me that there’s nothing critical about any of this – width, overlap, kind of tape, and so forth. Trying it is not a big deal – the tape is cheap, and it’s easy to remove if it doesn’t suit you. (Unlike machining a groove into a wheel, etc., etc.!)
