How To Use The Br 155 "energiecontainer" As Double Traction

Hey y'all.

After some Testing I found out how to use the BR 155 as Double Traction. While in Real Life the 156 wasn't originally able to be used in Double Traction, the 12 155's bought by "MEG" were upgraded to support Double Traction.

Now, to do it ingame:
1: Couple both Locos
2: In Both Locos insert the Reverser Handle and set the Reverser to the desired Direction.
3: Turn on the Traction fans in the trailing Loco, DO NOT turn on the Brake key in the trailing Loco
(3.1: Haven't figured out if this makes a difference, but set the Brake Force selector and Traction Force Selector in the Trailing unit to the same as you want in the Leading Unit)
4: Turn on the brake key in the leading Loco, turn on Power Supply if "ZS Aus" indicator is lit (this happens sometimes)
5: On the GSM-R, turn on Banking Comm in the Leading Loco. (Red Button in the top left corner of the GSM-R)

Now you have a working BR 155 Double Traction.

 

Curious. Never thought about the old banking comm making this workable in TSW. I know that BRO has a 155 double header in TSW precisely because whoever was in charge of the timetable was unaware that only some retrofitted 155s can do this, but not standard ones.
