Earlier in the thread is a picture of a K-28 pulling the full consist that I tried to recreate, that was the consist that finished the K-27. It is an impressive engine, especially with Rodney's improvements.

Yesterday I was able to take the K with the repaired gear out to Dr. Rivet's for an extended test run. It was pulling the same consist as it was the first day of his NG steam up. That is when I noticed a problem with the motor spinning upon backing up. It wasn't until the next day then 3 more brass Accucraft coaches were added that the problem developed going forward.

Yesterdays train had 11 cars; 6 brass Accucraft passenger cars (baggage, 4 coaches, and a parlor), 2 plastic Accucraft cars (combine and coach), 2 cabooses (one Bachmann Plastic and one Accucraft Brass) and a battery (Accucraft) box car.

On the level the scale measure a pull of about 1 lb. On the 0.6% grade the pull on the scale was about 1.75 Lbs.

Pulling just four of the brass coaches, similar to the added load for the Saturday run, would have added 0.25 lbs to the level load. So Saturday's load would have been about 1.25 lbs. on the level. I did not measure the drag on the incline.

I ran it for over 2 hours without any detectable problems in the drive train. I was using a Cordless Renovations Lith-ion 18.5v 5200mah battery pack through a REVO controller. It was still running strong when I packed up to go home. Thank's for the install Stan!

THANK YOU VERY MUCH RODNEY. I really appreciate the great service and help.

Train starting up the 0.6% grade.

Train after top of incline and starting on a slight downgrade.

Note added:

I have just weighted the cars in the train and the total weight is about 98 lbs.

The repaired gear box arrived in this afternoons mail and it is in the engine and running perfectly. Eight days from my mailing it to it's return. That is super service, especially with the the health problems Kristi is having.


Dirk:

The engine weighs abut 12 pounds and has a draw bar pull of 3.5 pounds. That is about average (30% of engine weight) for engines without traction tires. I'll measure the pulling weight of the passenger train the next time I'm out at Dr. Rivet's.

TO ALL:

Keep up the good thoughts for Rodney and Kristi!!

Dirk:

As a retired geologist, I know what big pieces of rock are for. I tie them to a rope and use them to hold my canoe in place when I'm fishing. Some have said that the only big pieces of rock I know about are between my ears.

Dirk:

I thought that is what sand is for.

I think that the Bachmann wheels are steel, but I don't know. The track that Jim uses is nickle steel, I think. I'm sure he will correct me if I'm wrong.

Stan:

That is what we hope for when we have a problem. I couldn't be happier.
