I've started a project I've been looking forward to for a while now. Converting my 2 Stewart Baldwin 'AS616's to SP 5201, a DRS6-4-1500 and 5225, a DRS6-6-1500. The main problem with the Stewart shell is that it dosn't represent any SP unit straight out of the box. It is close to 5203 - 5212 but is missing the stepwell gussets. Anyway, both units need the short hood battery boxes removed, 5201 needs A1A trucks, 5225 will have dynamic brake fans on top of the short hood and side screen openings. As I only get a few days per month to work on them, it's going to be a long project ;D. With and without the battery boxes  A closeup of the removed area with styrene strip filling the hole  Fans are only roughed in as I'm using brass tube for the shrouds.  |

Be sure to let us know how the A-1-A's go. There's several of us here that have been trying to obtain some for some lightweight Canadian roadswitchers used in the maritimes for quite some time now.

Will do. Are you aware Kato sell the trucks for their RSC2 as parts?  I'm not using them as they seem to have a lower bolster than the , Stewart trucks. |

I seemed to think that they had a different axle spacing

The axle spacing for the A1A trucks was at least similar to the Kato truck... the really hard part would be to create appropriate sideframes to match the axle placement.

I've looked at the axle spacing for Baldwin, Alco and MLW Dofasco trucks and they are all within a few inches. As Jerry said, it's the sideframes that will be the hardest part. In my case the Dofasco is nothing like what I need. The Alco A1A truck, either from a Proto1000 or Kato RSC2 are the closest but still need the drop equalisers and springing cut away (this depends on the mounting of the sideframe to the truck. Perhaps they can only be ground back so as to be not so obvious). Only the end springs can be left. With the sides then filed smooth, it's just a simple job to drill the various holes that were in the Baldwin sideframe. Looking through diesel data just now, the Baldwin A1A has a 10' wheelbase. Alco A1A has a 10'6" wheelbase while MLW Dofasco is 11' even. |

Miniatures by Eric makes the A-1-A sideframes for sure, as does one other company, it might be Kaslo but I'm not sure. Iomalley or M636 would know for sure. I still feel as though someone tried to build some using the kato trucks and it didn't work.

The kato trucks would be cheaper than a pair of custom trucks from Hollywood Foundry but the Hollywood trucks can be got in any configuration you want. It all comes down to price  |

I'm thinking of using the Commonwealth tender sideframes from a Monogram NYC Hudson snap kit. they have similar axle spacing and are easily modified into an accurate version of the Baldwin Truck. Plus they are cheap! Attachments:
