Marbelup Models announces the development of a 3D-printed "kit" of the Westrail AB diesel in Sn3½ scale.
Introduced in 1969, the AB class were a development or the A and AA class locos, being slightly longer overall and featuring an EMD 645E prime mover. The six AB locomotives originally carried numbers 1531-1536 (later 1501-1504). The AB’s were delivered in the WAGR green/red/yellow livery and were repainted in the orange and blue Westrail livery and later ARG liveries.
Basically, the "kit" will consist of 3D-printed parts for loco body, underframe, fuel tank and bogie sideframes, The general construction will be similar to the Marbelup Models D and DA, and DB locos, previously produced in Sn3½ scale.
The expected "kit" cost will be as follows:
The drive mechanism is based on smooth-running bogies by North Yard in New Zealand, same as used by the RailWest Models A class loco kit. The motor is by Auscision as used in their HO scale locomotive and is equipped with twin flywheels.
Assembly instructions are available online.
Kits can be reserved by payment of a $100 deposit per loco. Deposits are payable by PayPal (to firstname.lastname@example.org) or Bank Transfer via PayID (to email@example.com)
If you require the cab side numbers to be 3D-printed as part of the model, please specify the required number (1531-1536) or specify no numbers to be 3D-printed.
Expected delivery time: First half of 2021.
Deposits are refundable only if Marbelup Models is unable to deliver, for any reason, by the end of 2021.
Please note that Marbelup Models will not be producing complete locos in ready-to-run form.
