Title: Narrow Planet 009 Bagnal Saddlle tank WANTED
Post by: Terry Metcalfe on March 17, 2019, 19:01
My new layout is based on a temporary narrow gauge railway (tramway) which was built by the Canadian Logging Corps towards the end of WW1 to transport much needed timber from what is now known as Thetford Forest to the railhead and sawmills at Santon Downham.  I have called it the High Lodge Logging Tramway.

I know that there were three Bagnal saddle tank locos on it.

I know that Narrow Planet do a 3d model and offer a suitable donor loco for

Have you looked at various Shapeways offerings, such as Tyneside Models Bagnals here:

I think you will find that the cost of the Minitrains Krauss loco needed for the Narrow Planet Bagnal has gone up somewhat.

I would also not recommend using the Tsugawa-Yokou TU-KOPPEL-A chassis as the gearing is too high. But others may have had better experiences.

The TU7T chassis really are not a lot of good. They run far too fast and have very little torque so haulage capacity is next to non-existent. They are little more than a novelty.

The main problem if found with the Kopple A chassis both with and without a resistor is that I found that I needed to turn the controller up higher than desired to get the loco to start moving. Once it was moving the controller could be reduced, but if it stopped to get it moving again the controller needed turning back up.

I understand this is a direct result of the high gearing.

The result is that it was ok for just running around and around but it was not so good for shunting etc.

I understand that Nigel Lawton sells a replacement motor that is better than the original and the same diameter, but it is a longer motor so it will not fit in some of the kits designed for this chassis.

Nigel's 610 motor is an exact size replacement and is notionally 6 volts. His 612 also fits but is 2mm longer (taller?) so this may cause a physical problem. It does seem to have more torque than the 610 so doesn't suffer from the same starting problem. Nigel does NOT sell them as replacements for these chassis, they are just his standard micro motors at
