>>1809370>>1808369>>1808372For anyone wondering about the odd colour combination, my guess is a temporary solution. The 4012 had a special, deviating coating for commercial purposes. When the ICM-IV was refurbished to the ICMm-IV in 2008-2010, they replaced the 'walk through head' with a solid plate. The ICMm lost the ability to connect EMUs - this was decided because the connectivity mechanism was known to be very faulty. Hence, I assume the walkthrough system on this specific ICM was broken and they installed a solid plate instead.
