Here is some info about BR 155 locomotive:
1. 499 Euro for analog version and 599 Euro for digital.
2. Model is based on Marklin BR151/BR103 6-axle chassis and equipped with lightboards from Marklin BR143 electric locomotive. Specially modified version of VELMO LDS48568-I is used for digital version of loco.
3. About delivery time: actually a lot of important questions here. First, I need to know how much customers would like to order this loco. Then, I depend on availability of Marklin 88261 (BR151) locos, Marklin E262470 (double-arm pantograph) and Marklin E169435 spare part (lightboard from BR143). For example, 10 people tell that they will buy BR155. Right after this I need 10 Marklin 88261 locomotives (it's the only model with suitable 6-axle chassis which is in production by Marklin at the moment), 20 E169435 lightboards and 20 E262470 pantographs. To be more detailed, I expect a production of 20 locomotives in about 6 months. Of course, actual terms may vary a little, but I hope that production will go even faster.

5. Manufacturing technology - high resolution 3D printing. Painting: preliminary polishing, primer coating + 2 layer air brush acrylic polymer email painting. Industrial pad printing is used for lettering, logos and numbers. Model has many separately applied metal photo-etched elements (window frames, vent grilles, platform and handrails in front of cabin, frames for headlights) metal buffers (taken from Marklin locos). Roof equipment is also very detailed - there is a big number of separately applied 3D printed elements - insulators, dischargers, pantograph raisers and even radio antenna. It also has enhanced pantographs with diagonal bars. Thin metal wire is used for separate handrails and electric feeder on the roof. Windows are made from thin acrylic glass milled on CNC machine. Pantographs are functional and can transfer a power in analog mode (non-functional for digital version). Model also has a detailed driver's cab which is made from thin photo-etched metal with applied color sticker.
