This is a Siemens E-House, a prefabricated electrical substation used for power distribution, pictured here sitting atop an incredible previously-blogged MAN TGX truck and 10-axle Broshuis trailer, as built by TLCB Master MOCer Dennis Bosman.

Dennis recently started work for Siemens after an absence of fifteen years, and created this amazing load for his ‘Van der Vlist’ liveried heavy-haulage truck, and his Siemens colleagues.

You can check out the E-House, and the spectacular truck that’s carrying it, at Dennis’ refreshed ‘MAN TGX “Van der Vlist”‘ album by clicking here, plus you can click the link above read Dennis’ Master MOCers interview here at The Lego Car Blog to learn how he builds dazzling creations such as this.
