The PIKO model of the SP45 universal locomotive reproduces all the proportions of the prototype very well. The exact paint scheme and precise lettering are each authentically based on their prototype. The model has free-standing handle bars. Sharply engraved bogies show all the details of the original such as spring elements and axle bearing caps. The PIKO motor with two large flywheel masses provides excellent running characteristics and a large tractive effort. The model features a PluX22 digital interface. Prepared for digital operation with sound, the model can be easily converted at any time.
