Converting Broadway Y6b to Y6a ... how easy?

Sat Feb 8 17:12:02 EST 2020

Well done. Looks great! I may have to take that approach. 

Maybe you can do an article for the Arrow on how you did it?  I have several projects I want to do and write up, but I just don’t have the time right now. 

When I have contacted various model companies (like BLI who was at the Dulles train show today) they won’t do it because they feel the market for that is too small to justify the expense, even though the drive chassis is the same. I told them everyone makes Y6b’s but nobody in recent times makes a Y6a. He asked who else makes them. I understand it’s a business decision, but…

I started a conversion of a BLI Y6b into a Y6a a few months ago. I haven't finished all the little details, but I did go ahead and paint it. I cut the smoke box down with a cut off wheel on a dremel tool and rejoined it to the boiler. The down side is I ran out of room for the smoke unit to fit inside, so it got left out. I cut the catwalks and moved them around, moved the air compressor, mounted the feedwater heater and ran some piping to and from it. I practiced on an old rivarossi y6b first before sacrificing an expensive BLI. There's more I want to do to it, but for now, I'm happy with it.

Nigel, I have been lurking along on this thread, to see if I might try the conversion myself.  What kind of file is your attachment?  I couldn't open it.  Thanks

Jim, smokebox length is another item. Compare your model with pictures of 2156. I suggest downloading some 2156 pictures, then taking matching pictures of your model. Then comparing the areas that are identified as being different by you and other sources to decide if those differences are important to you.

I’d like to convert 1 of my Broadway Y6b’s to an “a”.  I’ve not studied differences closely (yet) so haven’t made the yes/no decision to move forward.  Other than the “elephants in the room” changes (replacing the left side pumps with a feedwater heater, adding the 2nd pump on the right, removing the fwh ahead of the stack, changing some piping/air tanks, etc.) can this conversion be done using the same boiler, cab, pilot and running gear?  I have a brass FWH for the left side and can get other parts from Cal-Scale/Bowser or ebay so necessary parts are easily available and lesser parts can be scratchbuilt.
